Hey everyone, I’m André, the developer of 9.8 in development for a year and a half now. It's been a wild ride but the demo is finally released as of the time you're reading this.

It’s a 2D space agency sim where you build and fly your own vehicles. For the demo you start with a small rocket and work through research, satellites and crewed flights towards a moon landing. The same builder also lets you make rovers and rocket-powered boats, so there’s plenty of room to get distracted along the way.

Production and marketing is going fairly well with 2k wishlists and some modest coverage by some creators and press. Hopefully things start to ramp up now. Full game is in development but should go into EA before the end of this year.

Steam: https://store.steampowered.com/app/4247050/

Happy to answer questions about what’s in the demo or how things work.

Hi! I'm developing The Undercity: Last Light, a side-view colony management game where you excavate rooms, organize workers and production chains, and deal with your colonists' needs and underground hazards.

I'm looking for fresh eyes on the first 30–60 minutes. In particular:

- When were you unsure what to do next, or why a worker/building wasn't doing what you expected?

- Did decisions create meaningful trade-offs, or did one option feel obviously better?

- Which screen or warning needed a clearer explanation?

This is an unpaid playtest. Playing is free, and you can stop whenever you want. Windows and Mac are supported.

Request access through Steam here:

https://store.steampowered.com/app/5253090/The_Undercity_Last_Light/?utm_source=reddit&utm_medium=social&utm_campaign=playtest_sep2026&utm_content=playtesters

Access is approved manually, so it isn't instant. The page also has gameplay footage so you can see whether it's your kind of game.

Feedback can go in the comments here or in our Steam feedback thread, also accessible through the game's feedback button:

If something gets stuck, a screenshot and a short description of what you were trying to do would be especially helpful. Thanks!

First, a big thank you to everyone who has already playtested Buried Worlds VR. Your answers showed me exactly where the opening lost people, and a lot of what you told me is already in the game: clearer controls, better guidance, and plenty of fixes along the way. If you took part, thank you. It genuinely made the game better.

I'm now looking for more Quest players, under the same conditions as before. Buried Worlds VR is a treasure-hunting game: metal detecting, digging and panning for gold across five real places where real treasure was found. I want to see where the opening still loses people.

- Pay: US$10 via PayPal, sent within 48 hours of your submission.
- Time: about 20 minutes playing plus a 5-minute questionnaire, any time within a week.
- Hardware: Quest 2, 3, 3S or Pro.
- Access: a free key, emailed to you after selection. Yours to keep.

- What earns the fee: play about 20 minutes, get at least $10 of finds in the game's own money, screenshot the marketplace, and answer seven questions on the site. A sentence or two each; one-word answers don't tell me anything. Stuck? Message me on Discord and I'll walk you through it. That doesn't affect payment.

- Eligibility: you must be new to Buried Worlds VR: never played it, and not in an earlier round. The whole point is to see the opening through fresh eyes. You also need to be 13+ (under 18 with a parent or guardian's agreement, and the payment goes to their PayPal) and have a PayPal account the money can reach.

In my game, Revive! Onsen Town!, I'm working on an underwater area where you can gather ingredients from the seabed and catch fish with a net.

Here's some early development footage. It's still a work in progress, but I wanted to share a peek at what I've been working on.

I'm still figuring out what else players should be able to do underwater, so I'd love to hear what kinds of activities or interactions you'd expect to find down there.

I've been building a space logistics tycoon on my own, and there's a free demo up on Steam. The shortest description I've got is "Transport Tycoon, except you're running a small fleet of freighters in one solar system,"

You run a freight company. Ports put out cargo with a deadline, you pick a ship for it, and then you plan the flight yourself: how hard to burn, when to flip and brake, whether to coast to save reaction mass, where to refuel on the way. The ships are fusion torchships, so a run is a constant-acceleration burn with a turnover in the middle, and the physics under it is real (constant g, flip at the midpoint, SI units in the sim). The orbits move. A route that's cheap this month is expensive next month and the planner keeps having to re-solve. No combat, no piloting. You plan, you commit, you watch it play out and deal with what goes wrong.

Quite a lot goes wrong. A hull has three systems, drive, thrusters and the hull itself, and each one wears with what you do with it: g-hours burned, dockings, tonnes handled. When one crosses its floor something mechanical happens. A worn drive gets capped at 0.15 g, for example, and every plan on that ship runs long. Captains have a skill and a nerve score; they get tired, and some of them quit. Solar flares dose any ship that flies through the front. A strike closes a port with two to five days' notice, which is enough to reroute if you're watching. The ships are individuals with a history, closer to Football Manager players than to units, and I'd like to think that's the part that sticks.

It's in active development. The demo is the current build, the numbers are provisional, and it gets updated often. I'd like feedback from people who play this genre seriously, especially on whether the flight planning comes across as a decision or as a chore.

I just wanted to share that I’ve announced the Early Access release date for my game, Cave Oasis at Shylake, for October 28! It feels like it’s taken forever (four years, including learning everything I needed to make this game so far, starting from zero with Godot and Blender).

It’s a quirky, nerdy, hopeful, alien sci-fi spin on a farming and small town life sim game. The main areas, story quests, and gameplay activities are all complete, and I got a lot of valuable feedback on the demo, including from this sub.

Everything’s ready to go, build approved, sending out review keys to press and streamers/content creators this week. Fingers crossed that this step goes well and that people like it. I know there are still plenty of challenges ahead, but I’m really excited to have gotten to this point. Wish me luck!

Hey everyone,

Following up on my last post: The first playable tech demo (v0.1) is now officially available for free on itch.io!

The game is a tactical, realistic wildfire RTS bridging the gap between games like WARNO / Wargame and the Emergency series:

  • Canadair CL-415 fleet: Formation flight, coordinated water drops, and high-speed water scooping (écopage) on the sea.
  • Dash-8 Q400MR (Milan): Airport-based air tanker dropping long red retardant lines.
  • Ground Forces (CCFM Trucks): Autonomous fire suppression and water cistern (DFCI) logistics.
  • Custom C++ multi-threaded fire simulation running at high framerates.

You can download the standalone Windows build here: Free Demo on itch.io: https://nomis3d.itch.io/wildfire-rts

Keep in mind this is an early prototype, so balancing is still work-in-progress. I would love to hear your feedback on the controls, flight mechanics, and overall feel!

Hi! I'm a solo designer making Mise, a restaurant management game for phones. It's free, plays in the browser, and needs no download or sign-up.

Every morning you check the prices, the weather and who's coming, shop at the market, build tonight's menu, then run service and watch the night play out. You start with a hot dog stand, move up to a sandwich shop, then a diner or a noodle bar where you hire and train your own kitchen team.

Here's the link: https://behuzer.itch.io/mise
Three chapters so far, a few hours in total. Best on a phone.

What I'd love to know:

  1. After day 1, did you want to play day 2? Why, or why not?
  2. Was anything confusing? Where did you get stuck?
  3. How long did you play, and what made you stop?

Honest is better than nice. If you'd like to help even more: Settings › Playtest log › Copy, and paste it here or in a message. It's just a list of taps and screens, with no personal details, and it shows me exactly where people get stuck.

Thank you and I hope you enjoy Mise!

Hi hi! I'm the solo dev behind Moonlit Grid, my first game.

Stupidly enough, i dont have much experience but my curiosity took over and here we are!

This is basically, a calm city-building game. You can create cities, customize and share it

There's an endless mode too and you can glide over your city as a bird

I am just mostly looking for feedback / first impressions and would love to hear from you:)

__

I released it on itch a few hours back here- https://hxlfed.itch.io/moonlit-grid

I've had flames as particles in my game for a while, but they didn't really do anything. So, I decided to properly incorporate them. They now increase temperature, let surface water evaporate and spread to neighboring terrain hexes under the correct circumstances, creating natural fire frontiers as they spread. they also burn the terrain and foliage, which slowly recovers over time, back to its former glory.

We're a team of two making Hostile Architect. It looks like a typical side-scroller, except you're the one designing the level, using stuff like ceiling spikes and lava pits and conveyor belts. You choose your traps, arrange everything, and then sit back and watch while a horde of heroes is unleashed to try to survive the level you built.

We've been working on this for about 10 months, not exactly secretly, but we're finally showing it off now, which is a little scary. Yesterday our trailer blew up on Instagram. But this is Reddit and you people are harsher critics. Does this look like something you'd play? Or should we throw ourselves into the lava pit?

Hey r/iosgaming,

Simon here, solo dev behind Tiny Harvest, an ads-free farming game 🌽

The game has grown quite a bit since I first posted, especially on the gameplay side I added a couple of new areas.

The core game is still:

  • grow crops and produce animal products
  • craft items through buildings & recipes
  • complete orders for coins and XP
  • unlock new areas and systems
  • use automation once your farm gets busier

Recent additions:

  • Blacksmith gear that gives bonus drops during expedition runs
  • Airport requests with destination leveling and better rewards over time
  • Farm Hands, so you can delegate repeated farm work
  • lots of balance, bug, and flow improvements from player feedback

Tiny Harvest is free to download, has no ads, and played only in portrait - choices I made because that's the kind of games I like most 😅

I’d currently love to get your feedback on the first session: does the early game explain the loops well, and does the pacing feel fair before the bigger systems unlock?

As a small thank-you, I added the code IOSGIFT (enter in settings) for some boost items ✌️
