In Freeze!, you control a sort of eyeball who is, level after level, trapped in a prison cell. Each prison cell has its unique design, and the idea is to help the eyeball escape from it.
To do this, as demoed in the game’s trailer below, you have to guide the eyeball toward the exit portal in every cell. Invariably, this task entails having to rotate the cell and having to do the act that gives the game its name: Freeze!
