amazing implementation of the theme!
the gameplay is really fun and I don't like puzzle games, so that means something!
some feedback:
1. I feel like the art is too blurry, i dont know if thats because you didnt change filter to "closest" or because you tried to draw shadows
2. there are too many elements on a small screen, I think a quick fix is just to make the viewport larger
3. I think the level names should have their own screen and then transition to the level it self, becuase right now its jumbles together with level and creates a mess.
overall amazing concept, you should keep working on it, and you might even wanna think about releasing on mobile as well that would be perfect for this :)
