Rotobo is a level- based Flash game by GlobZ where, from a top-down view, you handle a little robot which has to achieve the goal by jumping from platform to platform without falling in the surrounding magma.
As well thought as the game is, the interaction is very simple: the robot´s head is constantly spinning and its eyes tell the direction of the jump; by pressing and holding the left mouse button (or the space bar), you control its height and length; finally, when you land, Rotobo´s head starts to spin again in the opposite direction. But beware! once in the air you can´t change directions, and when you want to get the bonus items and finish the level quickly for extra points, thinking twice usually means one less life. 😛
In all a very nice game with solid visuals and gameplay, its only drawback is the lack of sound, but that doesn´t make it less amusing!
