Friggin' Amazing!!!
This game is truely great! Music has variation, the graphics are the best that they can be without lag, there's plenty of comedy: the references to real life people made me lol irl.
The upgrade system is effective, cheap enough at low levels so you notice a difference, and expensive enough at high levels to make it just about difficult enough.
The difficulty curve was superb, anyone who says otherwise just didn't give the game the chance it deserved. The levels themselves aren't particularly hard to complete so you keep the casual player happy, but to unlock all the acheivement provides literally hours of fun.
The difference between the bikes brings a pleasent strategic element to it (do I go with the fastest bike or the one that can get me the boost easiest?)
I managed to complete it in the end, getting first on the moon was definately the hardest (did it in sir colin in the end) and getting level 5 boost on Jaggies was a close second (the king ftw!)
The ending movie is great as well, I'm so glad it exploded otherwise I would have been pissed!
The ONLY thing that bothered me was the boost system in as much as you had very little control over it and I found that on particularly tricky levels I would deliberately have to not do a flip in order to save the boost for a flatter piece of track up ahead.
But that's a minor point that's only going to bother someone who's played the races enough times to know what's coming next.
Truely amazing game.
Really looking forward to whatever you make next.
