You, sir, are awesome
What can I say? You've breathed new life into an old, overused style of game. For one, I've loved {Rose} even before playing this game. For two, it was solidly difficult; and that's what I like, it's no fun being able to dodge everything. All of the pieces moved perfectly with the beat, and it was all very smooth. I thoroughly enjoyed it!!
Simple graphics, yes, but if they were any more complex it would be distracting, so you hit the nail on the head. The only thing I complain about is at the 'intense breakdown' part (about 45 seconds into the song), I was expecting to have a LOT more thrown at me for such an intense part; but I forgive you, if only because it would be impossible to survive if you HAD made it insanely difficult then, so yeah. =)
I love your games. You're a very talented guy. I especially like your 'Spin' series. Keep it up!
