The player must move blocks to create a path to the top as the tower slowly collapses or to outrun a boss that has special abilities.
There are different blocks that the player can move and each one has unique abilities that will help the player or kill them if it is a trap block. Additionally, there are various items that Vincent can use to help him in the Nightmare stages; these items can either be found during a stage or can be bought at the Landing between each stage. The Laddings are safe areas where the player can interact with the other sheep and can buy items. There are checkpoints during each Nightmare stage where the player will respawn if they die; players have 9 stages to fight through which is made up of 28 levels altogether.
