Great game, a little dificult but I thik that is skill issue, check my game too

At the first shop, you can get stuck under the moving platform and get pushed into the floor and stuck there.

I love the idea of powerups costing money - I only had 10 seconds left when I beat it.

If I were to change one thing before the deadline is up is that the jump feels super sluggish and slow, so I would definitely increase the gravity also increase the jump strength so you jump the same height but faster
