My review (Sorry for my English, I'm a Spanish speaker and I use a translator).
It's a game with good potential, but not very good execution. It lacks elements such as greater clarity in the controls and the game's objective, because I feel like I'm doing nothing while cycling. However, once you figure it out, it's fun. The sprite design is nice, and the music is good.
It's a good game, overall. If the controls were a little clearer, and there was a little more feel, it would be an excellent game.
That's my entire review. (Don't forget to review my game too.)
