I have a few problems with this. The game never tells you why you get a penalty at the start, and if you get a single one the first round, you can't come back from it. Making the timing more forgiving would definitely help here. Also, the required score scales too quickly, I got two + mult but timer spins and still couldn't make it past the fourth round. Speaking of the timer spinning, if the only difficulty you wanted to have from it was making it harder to get the timing right, I would suggest putting an indicator for where the 0 is. (If not knowing where the 0 is was part of the intended difficulty, then keep it, but I just wanted to point this out in case it wasn't.)
thanks for taking your time to try it out and give your thoughts on the game, not knowing where the zero is was intended to be a part of the difficulty but multiple people have asked that so i might rethink it, the score scaling was a bug, and I'll add a simple tutorial to the start to explain the penalty
