== THIS GAME IS OLD AND BAD, LOL ==
This game is very old, very outdated, and has lots of problems. The sequel, on the other hand, is a tremendous improvement over this game, and the upcoming third game in the series (TREBL: Rhythm Arcade) is exponentially better, still.
I'll leave this game on Newgrounds until TREBL2/TREBL3 get featured in the Rhythm Games collection, but please be aware that the series has improved far beyond this game. ;D
You can play TREBL 2 right here on Newgrounds. Check it out at:
