MewnBase

About this game

Be a space-cat.

MewnBase is a cute, 2D exploration/survival game. You land on an uncharted world only to realize you didn't bring any snacks and forgot half your luggage. But hey, at least you brought this workbench thing. You'll need to collect resources in order to construct a make-shift base. Craft a variety of different base modules, from airlocks to rain-water collectors in order to make your new home on this barren planet a little more cozy.

Other Neat Features

Technology Upgrades
Find strange, yet oddly familiar artifacts scattered around the planet. Research them to unlock shiny new crafting recipes and tech upgrades.

Manage Your Base's Resources
Build air cleaners to keep you breathing. All those modules plugged into a single outlet probably won't cut it. So you'll need more solar panels to keep things humming along. Keep a supply of clean water on hand to keep your plants hydrated.

Day/Night Cycles and Weather Hazards
It's hard to find your way in the dark. So fuel up your generators and make sure your base’s batteries are topped off before night falls. Then batten down the hatches during thunderstorms and gusty sandstorms.

Vehicles
Walking from point A to B is for the theoretical space-birds. If there were any. Construct vehicles to traverse long distances in style.

Community Localization
MewnBase comes with several community-provided translations for menus and gameplay text, including: German, French, Spanish, Portuguese, Russian, and Turkish.

  MewnBase v1.0 is now out!

  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.

  MewnBase 1.0 Release Candidate up for testing

  RELEASE CANDIDATE BUILD for v1.0 is now up on Steam and itch.io. In Steam you can access it by right clicking on the game in your library -> properties -> Betas -> and opt into the 1.0-rc version. Backup any saved games before trying these!! It's been... almost 8 years since the first version of the game was uploaded to itch.io - working on it sporadically throughout the years in my free time. But time to stop dragging my feet, and call this done. Really not a huge update feature-wise, really - but does fix a handful of bugs reported by y'all over the last year ❤️❤️❤️ COUPLE things I'd love to see tested out is some new tweaks to the behavior to the Refinery (shouldn't draw as much power when not actually producing Rocket Fuel), and also that the Autocrafter will now pull water directly from your base's water supply. (Water supply doesn't need to be adjacent to it or anything, just part of the same base). If you happen to find an issue with those builds, please feel free to report them to the game's Discord Server, or email me steve@cairn4.com The actual 1.0 update should be out before Halloween... no excuses, Steve :P
