I FINALLY beat the game! Damn son, I don't remember the last time I got so frustrated and mad at a puzzle game, but that means it's a good one. Infinite props to you sir.
I feel a like a lot of potential for a longer game was lost in the making of this game. The speed-up and slow-downs in the second "x" level could've been used more effectively, not to mention combining the 90 degree angles with the U-turns, or potentially all three thrown into a song. I would also LOVE to have a feature where players can upload a beat to one of their favorite songs.
