Happy Wheels is the portable version of the classic flash game of the same name, in which you must reach the end of a series of levels, controlling various characters riding wheeled vehicles of all sorts, from Bicycles to Segways.
The problem is that making it to the end of these levels is not easy, and it is by no means certain to happen. It's more likely that your character will die again and again in the most horrific ways possible, filling everything with blood.
The touch controls, despite what it might suggest, work pretty well, and the game by itself is extremely difficult, not to mention the frightening characters.
Happy Wheels is a very entertaining game, which, admittedly, is not for all types of audiences with the high level of gore. However, it is very fun for those who dare to try it out.
