Well, I’m having some problem coming up with ideas here. Or more accurately, deciding which out of my candidate ideas are good ones. Here are three of my candidates:

1. Robots in a facility trying to escape except one of them is for some reason (to be decided) temporarily unable to move. This immobile robot provides advice to the mobile (player character) robot. “It’s dangerous to go alone, take this advice.”
2. A cat with a cannon that launches itself takes on an invasion by the dog and bird alliance. Cannon being both the cat’s only weapon and means of long-distance transport. Thinking more like a platformer instead of one of those “press button, launch thing, hope for the best” games. And the cat has some ally who delivers some new neat thing every level. (“Every level” already ringing alarm bells for me here.)
3. An average guy wandering down the street before he suddenly gets some improbable weapon thrown out at him by a clearly insane person screaming the theme at the top of their lungs before disappearing altogether, and then beat-em-up with increasingly bizarre enemies or something.

I haven’t really got anything else here. I already had to sleep through the start of the competition. 7.5 hours gone and I don’t even have a concept yet. Aaaaagh! Curse you, sleep!
