Rather than what the other people said, I think simply just having no timer between the moves switching would be better. Otherwise, this is a really cool concept with elegant art that gets the main points across! Would love to see more of this.
I agree that the cool down can be annoying, but without it you can basically fly, although that wouldn't be that much of an advantage in the cramped levels.
(also, a little detail I added, the character flashes all of the sides of a die during the time of the timer cool down)
