I actually added the prompt because I was 100% sure while testing that I had the time right, but clearly my code wasn't accepting it. Turns out that every time I had set the clock wrong and the code was working as intended. I felt the prompt was necessary to keep players from raging at the game.
I was considering difficulties initially, and may add them in later. It would adjust the timer, hand movespeed, and maybe include number markers and the prompt being on/off. Just some small stuff to create the ideal challenge.
