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.

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