Wow it really speeds up hah. Fun gameplay and good challenge. Cycling through the colors is a bit more tedious than having a button to select a color but It fits the theme B) Great job!
In little time we had I tried to optimise the speed and rewards to provide decent challange.
I also think that assigning 1 2 3 4 for states would be more enjoyable, but as you said, we went for the theme :)
Thanks for comment!
