MewnBase v1.0!

Hard to believe the dev-log entries that say I started working on this little game way back in 2015 ^_^;    Spoilers: scroll way down for a few old screenshots from back then.

If you're reading this, thank you: for giving me the opportunity to continue working on this goofy game in my spare time, and for your patience as I slowly added in new features and fixed bugs - soooo many bugs that I never would've been able to find without the help of all your forum posts and messages.

It's been hard to figure out how to wrap up an open world survival game, and to know when to finally transition the game out of Early Access. I know calling this game finished might disappoint some folks - and I get that. There's always been a mountain of cool ideas and features that could have been added - but I've always tried to be realistic, and that I knew that I wasn't going to be able to add in everything. And after 8 years of using a code-heavy framework, I'm really itching to be able to dedicate more time to new projects with new engines and tools. That said, I'll keep trying to fix bugs and problems as people find them.

It's still definitely a game I'm proud of - even if its not the biggest, or most balanced survival-craft game out there. That's okay. I certainly enjoyed and learned a whole lot while making it, and I hope you all have had fun playing it. <3

I'm sure that Space Cat will get a chance to fly and explore once again in the future.



  • Lots of new sound FX for the Launchpad and Rocket
  • New Flag buildable that can be painted
  • Auto-Crafter can now use water from its base's water supply
  • Localization updates
  • Updated libGDX to 1.12.0

Bug Fixes

  • Water Supply modules now remember what color you paint them on game-load.
  • Fixed an issue where "no weather" worlds didn't have wind, and some other issues that could have prevented the mode from working properly.
  • Issue when crafting a workbench from HUD button with a full inventory would result in lost resources.
  • Fixed a mouse-input issue with the Dozer trunk and placing items.
  • Clicking on another inventory slot now cancels any active tile interactions / harvesting etc just like scrolling with the mouse or walking would.
  • Fixed issue where inventory items that only allow 1-per-slot could sometimes be stacked/combined.
  • Fixed issue that would stop the footstep sound FX if you interacted with an object.
  • Artifact number in the "Research Complete" popup now matches what is shown in the Research Log.
  • Fixed some sound FX problems with base modules (like Generators) that are close together and running at the same time.
  • Fixed an issue where the Water Spigot wouldn't be active, even if your base had enough water in it.
  • To prevent physics issues, turning off vsync will still cap the game at 60fps.
  • Fixed issue with the Game Over screen when pressing ESC.
  • Fixed an issue where the Refinery would still consume Oxygen and produce Fuel, even without power.
  • Fixed an issue where the Paintbrush would be selected, but the color-picker still wouldn't be visible.

As always, a huge thank-you to everyone that has helped report bugs, either by sending me crashlogs or posting them on the Discord server!


Here's a few old screenshots from the game over the years :)

The earliest concept of the game, was just some pixel art I mocked up after having listened to The Martian audiobook.

First working prototype. Probably still with grid-based movement.

Original crafting menu, we can see some more familiar module artwork now appearing in the background.

Finally, one of the old versions of the HUD. Overall art-style taking shape. But the game still just called "Moon Base" - and the main character wasn't Space Cat yet...

I bought it 5 years ago. Always so fun.

😁 Great Job!

I don't remember and can't find any record of how long I've been keeping up with MB... but wow, kudos for 1,0!! <3


worth the wait

It's such a great foundation, if you're done working on it, open source it and let us build more!
