It feels like every level is the same, and there is no real challenge in my opinion. Nice but forgettable (sorry to say it like this...).
Two "bugs" to report :
- clicking the "Next Level" button should bring me to the next level, not to the level selection screen ;
- at the end of level 3, I get the "New bike unlocked !" message, but if I go back to the main menu to select it, everything is as if I did not actually pass level 3 ; how should I know that I am supposed to click "Next Level" before choosing the other bike ? (but hey, what is the interest of the other bike whatsoever ?)
