Neat, original concept! Puzzle games generally aren't my style but I found myself enjoying this one quite a bit. Aesthetics are minimal, but quite pleasing, which isn't too easy to pull off! The sound effects are satisfying as well. The setting and flavour of the game are really well done! The controls were also very intuitive. I didn't figure out a control on the keyboard to press "start", though, which made me have to take my hand off my keyboard to click it with my mouse.
