This game is freaking terrible. If you aren't completely perfect, then you cannot complete the level. There is no slack whatsoever. I mean, if you mess up just a little bit, then you're done for. It's BS.
The concept was very fun, but the level of perfection required is simply unrealistic.
Nice graphs, and the perfect amount of difficulty. Not a 'pull your hair out' sort of hard, yet not easy enough that the game is boring.
I enjoyed it. 4/5.
