The audio sells the setting, I think having consistent the pixel sizes for the sprites would unify the art style a bit more. I beat the whole thing using ranged mode, I couldn't get hits in with melee since the cooldown was so long so it seemed inconvenient to hit anything near by-still its a nice idea, I can see how the enemy variety would encourage using it. I wish there was even a little bit of visual feedback when hitting enemies since that would probably improve the game feel a lot.
