A game with different win conditons every level, where you must fufill none of the conditions to progress. like if the condition is to fall down a pit, you should stay above it, or if the condition is to touch a flag, well you'd better find out a way to die without touching it! The condition can be more then one thing like: collect at least 5 coins and then touch the flag,falling is ok. you would have to collect less then 5 coins and then touch a spike.
