Hello! We have pushed out for both the Demo and the Full Game, both containing fixes for various issues and upgrade to GMS2. The game now defaults to booting in Windowed but can be changed to fullscreen via the options if you don't have issues with the black screen. If you do in fullscreen but want to play it like that then please try the Borderless beta which should hopefully fix the issue. Saving should now be pretty much fixed, if anyone spots anything not saving please let us know via Steam Forums so we can fix it! With the introduction of saves you can now modify certain things such as your own inventory. You can also change your stats (Health, Hunger etc). You can find this in your appdata local folder. Demo is still the same but features fixes and changes based on the full game but of course still does now allow the loading of saves however the game should still save so you can transfer your save over to the full game. Depending on what is done first we'll be hopefully releasing the Level Editor or the first test of bandits in the next update.
