I liked the game, but it can be improved. The AI is very dumb. It basically drives to the outside of every corner when turning, rather than taking the best driving path. On some maps many of the AI cars get stuck. The only reason the game gets harder is because your opponents get faster than you at higher levels. I would rather see the AI do its best to follow the best driving path and have the difficulty increase based on level design while the cars all stay the same speed. The bridges covering parts of the five last levels can be annoying, but that might me intentional.

PS How do you unlock the purple car? I got perfect on every race and only unlocked the black one.

Its been a long time not seeing this kind of racing game !!

Great game with nice music, i love it, and maybe some minimap will be great for future version like user222 said...

Cool circuit racing game, I kinda liked drifting around corners and smashing into walls :) Maybe a mini map and 2 players option for future version, if ther is any :)
Btw, why does sometimes when entering in corners, there is a strange feeling over the car?

Fun and smooth, good job.
