I understand the controls are supposed to emulate a realistic experience trying to steer a raft in water, but it is not proportional the the forward auto scrolling speed of the course.
The other issue is what is wrong with Level 4? Why is it automatically game over as soon as it loads? Please tighten the screws and fix these flaws and glitches, then the fun factor for your game will increase dramatically as it is overall a decent start to what could be a fun time waster type of game.
