Pretty cool game, feels like the binding of issac combat wise but the upgrade system is pretty unique! Goes without saying but the art is the highlight and really amazing part of the game, even how the bullets have a few frames of animation where they're slightly rotated is so cool! The only main issue I have is the collider of the right door, I don't get why it's a physical collision as you can get stuck on it during a fight , I think it would've been nicer to have it as a trigger collider and not change the shape of the level collision. Otherwise gameplay is pretty fun, maybe enemies could use a bit more telegraphing though, excellent work, such a cool visual style!
