Challenge, but needs intro levels
While most talk about muscle memory with this game, its not quite right. Sure, you need to know how long to hold and release, but you do not develop "muscle memory" when there is nothing to remember.
The randomness of the gaps even from the start prevent the memory. If the game did not reset the targets each round then the start would be easier to develop some memory.
