Great idea, it looks good, but the game just didn't click for me. I did not enjoy having to keep track of the timer, it felt forced. Might be just me, though.
It's allright I realized how hard it was only when it was too late. Having you keeping time was an idea from the beginning, it's supposed to simulate having to keep an eye on a lot of things at once. I did my best to try and make this fun :D
