Gameplay

In order to beat a level, the player must make it through all the stages and the boss battle with just 3 lives. If you survive a stage for 30 seconds, you'll be advanced to the next one. Completing two stages will grant a checkpoint; if you die, you'll be sent back to the previous checkpoint. You're allowed to use checkpoints 4 times per attempt. Every stage is a different pattern that must be learned and overcome.
