^ I felt the same way. Just give me 3s, 1s, and 5s all day. Even if the time to release was shorter so the game was more about reacting to the dash you got rather than just hoping you don't get 2/4/6 again.
The aesthetics were nice as well - especially those dash lines. I would suggest making the platforms darker - it took me a little bit to realise there was a second platform on Stage 1 (where the tutorial text is) as I thought it was just a single platform practice level for a bit.
