I like the idea of playing a paper aeroplane soaring through the sky of a child's bedroom! And the ever-changing controls mimic that feeling of total uncertainty when you throw one of these things and you have no idea how far it's gonna fly, if it'll fly at all, etc. I do think you could've gone further with this idea, though - really sell the kids' bedroom and imagination aesthetic and feel with a more childlike-feeling bit of music, and maybe outside of the movement area have things like passing clouds. Do more to sell the game's mood, and I think you'd have a real neat minigame here! Nice work!

Decent, if not all too original take on the theme. It was a bit frustrating that there was seemingly no cue when the controls changed, and when I pressed a key to control the plane like in the previous wave but now it had been changed, I would get the "Control Error!" message and the block would fly right in my face with almost no time to react to the changed controls
