Horrible.
Good idea. Good concept and stuff, but it was just amazingly... bad. I can't believe I even turned off my music for it. Next time, make it more appealing. I played it for 5 minutes and I already knew it sucked. Maybe try to be less lazy and make an instructions page. Unless, I missed it because I wasn't paying much attention. No one wants to take a shitty tutorial because those smell like ass.
