Nicely polished. The concept feels a bit basic to me, though I like the way you tackled the "control jumbling": clearly telling the player that the controls were switched, but leaving it up to them to find out how, while still keeping it doable by limiting yourself to three keys. I found that many entries that did switch controls around used the whole keyboard, thus ended up nearly unplayable, even though very adherent to the theme. Glad you prevented that - had some good minutes of fun!
