Thanks for playing my game, I'm glad you liked it! It's good to hear that the effect of the music speeding up worked.
This thing with the green clock in level 2 is really strange, it's working fine for me - one thing I can think of that's not explained very well is that the green clock needs a different sequence of button presses to the red clock (so you have to press left, then right, then left and right together, and that pattern of three presses repeats) - was this the issue or is there something else going on?
