I dunno, browser flash app isn't really the place for a rhythm game. About 80% of my errors are due flash lagging up for a few seconds here and there, and even if that issue were to go away, it would still essentially be a bad version of Stepmania.
I feel like flash should be used by small teams, or individuals, to make something small and really creative even without a lot of resources at their disposal. Not to recreate something that's already been done better by consoles or by other applications with more juice.
Love this game, it's so funny. I'm glad there are finally badges for it, but I wish they were harder...I haven't played this game since they had a card for it ages ago and I still got both badges within 30 mins =(
