Thanks for the feedback. Yes, the AI is minimal :-/
Great idea about more kids becoming ghost ! It give me some fun ideas ! :-D
I have though about reusing the ghost sprite floating above when loosing, but not as a gameplay feature.
I will first finish the tuto I was watching for learning making 2D games in Godot because I was learning and then I tried to do the jam on a whim. It was my first game with Godot and doing tilemap so I made mistakes about it I think.
