flash is outright broken.
Clicking instructions causes it to crash to white, clicking the menu buttons don't always result in the action intended, and clicking "ok" to get you into the game itself doesn't even fucking work.
Everyone complaining that it's offbeat is playing on a comp that can't handle it. Works perfectly for me in that regard.
This would rock so hard if it didn't lock up every time I completed a song, then make me redownload the entire thing again after I refresh.
