wow super polished, the menu and general presentation and of course music is super slick.
Unfortunately I also felt like the timing was a bit off. I remember playing a rhythm game once (may have been crypt of the necrodancer) where you could actually set an offset to the timing, set the timing to be a few milliseconds ahead or behind the track. Even if it isn't "correct", if it feels good to the player, that's all that matters, right? I think something like that would add massively to the game.
Nice entry though, thanks!
