Hello. That's weird : none of your 2 games work on my computer. A screen appears and then is gone. However other Godot games work fine on my machine. Are you sure that you have shipped all the files that go in the build ?
The graphics look very interresting, though.
EDIT : I have seen that other poeple have been able to play and rate you game in the Jam. So, it must be on my side ...
