It was meant to be a game but we totally forgot to add a score saving system allows you to withdraw and save your score when you are out of keys or whenever you like to. Also there were a climbing and clinging system at some point of the game but because of some later bug we had to remove it, that system was the reason there are more points outside the walls. With the addition of this two little elements it might have become a weird and addictive arcade game. But yeah, it is just a toy for now :)
