I played till the end, maybe the graphics could be improved, but the animations are top! They really add to the fun of the game. I liked that there are multiple ways to "realease" a new soul. Maybe you could add some limitations for more funsies? Like "Swimmer" (can't be drowned) or "ZooKeeper" (not affected by snakes). That would add a bit more of challenge and variety.
Overall very interesting for a first game using GDevelop, hope you keep trying the engine!
