The character controls and platforming feel great and are really polished, just like most of the game.
But I do have some critisism for the game as well.
1. The Camera zoom-in is a cool idea, but it kinda defeats the purpose of change the size since it doesnt feel any different. Size is relative, and since all other things are small as well and the camera gets scaled down too, it doesnt feel any different being small or big. I would maybe suggest playing around with either keeping the camera the same size or if you cant see the character well enough then you could only scale it down a little, so that the character still seems a lot smaller but you can see more of the room and its relative size.
2. There is a lot of waiting and walking involved that definetly needs to be cut down
I think with both these things improved this game could be really good, I especially like the sound design!
