The touching the block to make it timer go down really stood out. My only criticism is the jump didn't feel that snappy. But these are small nitpicks to criticize, especially for a game made in 4 days. Also, the final boss was really a nice touch to finish off. If you get a chance, I made a countdown-themed puzzle-platformer too (Mr. Blob)—I'm always curious what other jammers think of it.
