RoboBall is a game in which you control a ball-shaped robot and solve
physics- and logic-based puzzles. Your goal is to control various
mechanisms in order to reach the end of the level, where you will find a
teleporter that will take you to the next level.

Puzzles

On every stage you will find a large number of different mechanisms,
buttons, laser switches, and doors. To open a door, start an elevator, or
simply activate a certain mechanism, you will need to activate a button.
Sometimes you can't do it by yourself and will need some help from metal
balls, barrels, or crates. But don't forget that they might also need your
help to perform certain actions.
