Rhythm game, but has some major flaws that made it not great.
So the reaction time necessary was a little too fast, you end up failing almost immediately if you haven't memorized the patter already. Major bug was that the music looped over itself every time you tried again, causing ear rape in about 5 restarts. I wish you could just press space to try again, and keep things simple in that regard instead of going over to your mouse every time.
Ultimately the concept was good, but it was executed quite terribly.
