Interesting premise! Having to keep track of the amounts of activations of the inflation/deflation as well as the jumps was quite interesting. The level design did not really support the game mechanics. The movement was a bit floaty but the levels required precision in your jumps. So there's a bit of a contradiction there.
I only managed to reach level 3 before giving up after countless tries unfortunately.
I think if you were to lean into a more forgiving level design that complimented the wacky movement, you could develop a quite fun and quirky platformer.
I do love the artstyle though, the player characters design is fantastic, reminds me of pizza tower :)
