Maybe not the best place to put it (as it is a casual fun thing I did), but i finished my first speedrun of Portal done Companioncube (PDC):
Its X-tremely slow and derpy, but hey, it was done in 1 evening. Im panning on redoing it a bit faster in near future.
Feel free to tell me what you think or do it yourself (Id be happpy for some competition
