The game is set inside the creaive part of my brain. (note the blandness) As you progress each level the mind has a Brainwave.
Ideas come in the for of pushable boxes that must be placed into the holes in the walls. When the holes are filled in a room and due to the brainwave you enter a more complex area. As you progress you have to contend with complex ideas in the form of barriers, evil thoughts in the form of painful red squares and distractions which take to form of nasty little face slicing critters. Its actually quite entertaining even for me and i'm making the level.
Oh and later you are given a time limit and if it runs out I get bored and my mind shuts off erasing everything, even you.
