I think the concept is great, a platformer where you scale things up and down is quite common on the jam, but having limited arrows really sells the puzzle. I think the game is at its best with resource management in mind, give players limited arrows, and many sponges to shot, and you'll have a great puzzler. I'm not too fond of the controls, however, specially when you shoot. If you face left, you can't shoot right, and viceversa, and also, it really is frustrating when the arrows don't hit the sponge I'm aiming, maybe turn it into a shrink/growth gun and take aiming out of the game? Overall, it's a great twist on a somewhat common idea, but the execution could of have been better.
