I quite enjoyed this game, having to mentally count the time while solving puzzles was a nice twist to a well known genre.
I do wish there was another mechanic to incentivize you to want to push your luck with the timer. Like if you could make money by clicking a computer, but by doing so, you risk waiting too long and missing your clockout time.
I also felt like the moving checkerboard background was a little harsh on the eyes.
Overall though, a great first game with a fun mechanic. Good job!
