Almost really good. The graphics are sharp as hell, the music is catchy, and the gameplay is tight. There are some major issues with gameplay though. First, I really don't like how you have to use the spacebar to take back a move. Implementing the scroll wheel as an optional alternative might have been a nice way to make sure the game maintained a mouse-only control scheme.

I think different modes might also have been a nice idea. The time limits were really daunting to me and made me feel uncomfortable about experimentation, especially with such a unique game as this. The bonuses that you collect were a nice way to mix things up, but I wasn't able to get a very clear view of how many there were in a level, and that was also kind of discouraging.

Anyway, I feel like this game would have been really fun if you'd had some kind of racing mode, collecting mode, puzzle mode, etc. instead of one linear campaign that seems to assume everyone is comfortable with the control scheme before they are.

fresh idea with minor problems

Overall the game is really good and it's challenging as well, a dangerous combination but in your case both work perfectly. But still it has some problems, the pointer and the curve direction can be easily confused with the background. Maybe a change in the colors would make this game even better.

Simple and fun.

Quite refreshing to see something new and creative. It took a bit of tries before getting the hang of it, but it was enjoyable.

Really awesome game.

Very innovative and new. Great style and graphics, and it runs perfectly smooth. 10/10, great job.

Awesome

Challenging, but fun! Thumbs up!
