We just uploaded a new version with some minor bugfixes. The update is so small you likely won't even noticed it updated at all.
Furthermore we want to inform you that the F12 button WILL restart your game and will NOT take a screenshot.
This is a famous problem our engine has, and we have not succeeded in fixing it. Please be aware of this, as the game will restart without saving. (Sorry, if it happened already)
Humble regards
rest.less Games Team
