I like the concept but it's extremely repetitive and it becomes way too challenging too fast, then sometimes it's extremely easy. Also, there are bugs. I often hear the beep very long after hitting restart, and sometimes the highscore window pops up after I already started a new game.
Also, I take back my initial rating of 5 stars because in real life this would be extremely easy, whereas clicking the small color area with a cursor in a score sensitive time limit, is too stressing for anyone. Especially when many wires are tangled together in the exact same spot so you can't tell which wire underneath the top wire is the right one.
