Effective use of the premade sounds. The art style is really nice as well. As far as the core gameplay loop, a more direct implication of how your character can move would help - like flashing the keys up with the movement icons before you start playing. The overall experience is really great once you get an idea of what to do, and the delay mechanism is really tense!
I'm not sure if there's a way out of the death-spiral, though; once you lose enough moves, the game can become impossible and the fail state seems to be awkwardly staring at a motionless character. More to come in future updates, I guess?
Anyway, fun concept, and I enjoy that the mechanic that represents the Game Jam theme actually ties into the game's overall vibe, when so many games in this jam just include control manipulation as a gimmick.
