Skull Daddy is a physics-based puzzler that is currently only available as a demo, bundled with ten short levels and a limited number of tools to choose from. In each stage you are assigned a limited number of basic building blocks to construct platforms with, so that the titular character can roll his way towards the exit safely.

Instructions are relayed to the player via sign posts that can be read or ignored at their own discretion, and you can retry a level as many times as you like until a working solution is found.
