Quick gameplay explained:
Enemies only die after they are fully painted and hit with a melee attack (or with your teleport spell on E)
Walking on unpainted tiles will hurt you, enemies remove painted tiles.
Enemies move after you move 2 times or when you wait for too long
If the game shutsdown at the start menu for unknown reasons:
restarting it a couple of times might fix it
