Gameplay
The object of the game is to tap and hold the stylus down against the screen at the right time to fuel up robots in order to make them functional, as well as releasing at the right time to prevent overfilling it. Filling them up too little or too much can cause them to not function at all. There are two kinds of robots you need to fill; a thin one (4 beats) and a fat one (8 beats).

Hit or Miss

 * Hit: The robot will fly off if perfectly filled or do a little dance if just filled the correct amount for a hit
 * Barely: The robot will appear dazed and tilts its head from side to side if underfueled. If it is overfueled, it will grab its head as if it were about to explode, with its eyes growing large and small.
 * Miss: The robot will continue down the conveyor belt if the player does nothing. if the player misses while trying to fuel, the robots head will tilt to the left. If the play fills the robot too little, it will have crosses on its eyes. If the player continues fueling too much, the robot will explode.
