Unlike most platformers, the player can't jump. Instead, the player must flip gravity while standing on a surface. The player utilizes this to traverse the game's enviroment and avoid various hazards, including stationary spikes and moving enemies. Later levels introduces such as moving floors or rooms, which upon reaching one side, the player emerges on the other. The game has 8 main levels inside a large world which the player can freely explore. Due to the high difficulty, there are many checkpoints that the player resets to upon death.
