I loved the rhytm of the game. The concept is pretty simple but it works. The scaling of the difficulty is disappointing, but I saw that your intention was to create a speedrun game, not a puzzle one. Now, while I totally understand your decision, I think that you could still be more creative with the level design, just to put a bit more difficulty and variety to the game. Consider updating it in the future, the idea is good, it just needs more time spent on, like most of the games in the jams, including mine. Keep it up.
