Happy new year to everyone. The new version addresses the various corrupt save errors triggered on some save files All version should load and save properly now.
Hello everyone, At the suggestion of a community member we've update the PC version to the one running on a different platform. We also added full Steam Input support for controllers so the game can be played on the Steam Deck too. Enjoy and happy new year!
An update is being processed right now. Besides small fixes (running properly on screens with DPI Scaling, fixing the Caveman achievement unlock) we have tweaked the graphics engine and it should allow more graphics cards to run the game.
