This game has some cool ideas. The fans interacting with the bubbles are huge. I loved that. The puzzle elements were pretty fun to figure out, and not complicated at all, although I do wish there were a few harder ones.
As a platformer I think there are a few improvements you could make. The screen size compared to the window size is incredibly small. This is definitely unintended too since when the screen is supposed to go black, you can still see the borders not being covered up.
The jump feels a bit too floaty for me. For the distance you go while airborne you get a lot of air time. The walking speed was also a bit slow, but maybe that's because the window was so big and it just felt that way. Up to jump is also a weird choice for a platformer in my opinion but that's totally personal preference.
Fun game!
