Is it just jumping on thing's heads or is there an actual plot?

The protaginist (MegaLinkMan thing) wakes up in a world that is created by a higher being who is hell bent on making your life a living hell. This creator communicates with you throughout the playthrough. Another character that communicates with you is the villain's bigger brother who is fed up with his little sister (the villain) tormenting test subjects. The brother therefore helps the player in anyway he can and this creates an unusal relationship between the three of them, also allowing the use of cheeky humour wherever possible.
