I like this, the art is pretty cool, and the gameplay is pretty unique! I like that you need to move using the gun's recoil, and that you need to simultaneously defeat enemies and avoid obstacles. The sound effects were also pretty nice.
I think the game could benefit a lot from faster movement, specially considering it's a fast-paced game. Aim also felt just a bit weird (though it's not that big of a problem and could just be me)
I really like this one, and I think this has great potential, good job!
