Really cool concept well executed. Some sounds and maybe music would have been nice, but obviously not needed.
The game actually gets quite difficult after a while, which is great. I made it to a score of 3937, don't know if that's good or bad, but it was fun getting there. I also really like the "Job Rules" with the "Got it? No" starting the game, lol.
Good job, you made a very cool game!
