Cool game. Controls are responsive, like the theme and all that. I have one nitpick and one actual criticism for the game in its current form:
Nitpick: Imo the player shouldn't collide with the chunks of enemy on the ground
Actual thing: The camera seems to kinda freak out whenever I get near a wall, and moreso when I'm near a wall and the paper airplane is nearby, it caused it to rapidly shake and zoom in/out on several occasions
Still though, I really like the vibe and gameplay so far!
