Replying to Contest idea?

well i was on the coc page and started playing that gnarshmallow game and i thought if it would be a cool idea for a contest if that game made an option where you can record yourself playing, and a contest could be made for like best trick or lap or something, maybe the winner could get stuff from the like sponsers of that game, idk im just thinking out load might be really impractical or just a bad idea, just thought id post it see what happens thanks
