Cool Ball — About this game
Cool Ball follows a bouncing hero through time to find Suzzette, who has been scattered away by the Big Bang. Steering is only part of each room: you must cover its platforms and gather what the route demands before an exit appears. A high bounce reaches places the normal rhythm cannot, while one-way and shrinking platforms make the order of travel important. Later obstacles ask you to bring the right power-up, such as a hammer for a brick wall. Level passwords let a carefully solved room become the starting point for another session.
Choose Start Game with up/down and START to enter level zero. Steer left/right and tap A or B for a high bounce. Inspect the route before using a shrinking platform, then record the password after clearing the room.
