What if after you 'win' by accumulating all the time there's a cutscene of Jerry standing up and then he chases you around all the rooms and you have to find the exit in one of them to really escape while Jerry is taunting you the whole time through dialogue appearing on your screen (hopefully shaking or something) and then it's like a dystopian/utopian world (no clue which one would be better) and then it shows 'the end' and then, in like letters written in blood or something slowly writing out 'or is it?'
Sorry the idea is so unrefined. I think it does have potential though, and I would love to see it implemented :)
