Thanks for playing!
I have the arrows moving on the beats only, so its easier to feel it when the game is synced nice. The download syncs so much nicer than the web browser, and has fun lighting effects too! It's been a few years since I've played any rhythm games, so I'm not at all surprised I am using a non-standard control scheme. I had my wife playtest it when it was done, and she was like " ... ummm. but the arrows go UP in DDR, and they never have more than 2 at once", I completely forgot! Too late now.
