Fun idea, and interesting interpretation of the theme. With some additional layers I could see this turning into to something really fun.
The camera rotation felt more like a bug than a feature and if that is the case, it might be worth looking into the order precedence of the euler angle rotations for Godot and why that’s necessary but it may even be necessary/easier to use quaternions. Something to look into at least just so you’re aware of how to fix those sorts of issues.
Regardless, this still played well enough and was a solid first GWJ entry. Nice job!
