Here is a random game concept.
Don't even wonder why I came up with this idea.
The game would be kinda similar to Lemmings (deadly traps and a bunch of stupid creatures) with some endless running stuff (or not endless, whatever). Each sheep would be controlled by a single player.
The goal is to keep your sheep alive as long as possible, by dodging, jumping, slowing or accelerating.
The twist/original thing is that some traps are forced to kill some sheep before the other can sheep pass it (something like Deaths in the list here : http://www.venbrux.com/freeware.php ). Some other traps would just crush the middle or the end of the horde.
I think it could be really fun to see how people react.
Edit: If someone is interrested you know what to do!
