とても難しいですが、反射神経が鍛えられますね。

BGMがゲームの雰囲気にピッタリ合っています。

Good game, I really like the music, and the graphics are good too.

Very cool game. Cool music (a bit ripetitive) cool idea, fun gameplay, maybe too hard or maybe my skill issue. Good work

Fun idea! Reminds me of guitar hero

Everything i good only the control 

you need to be able to change circuits with arrow keys left and right, but nice game and fun to play :)

That is cool idea. I love it! but it's too hard for me

high score of 56, cool graphics, would love if I could change circuits with 1 2 3 keys, but that's just a nit pick. Nice game and good job!
