Decided to go with the walls closing in on you, a la Star Wars. You'll have to grab as much treasure as possible and reach the exit which will be at the top (for now).

Betcha can't guess which game engine I'm using :wink:

Feel free to 'play' this awful version -- I'll be updating periodically so who knows, maybe it'll be better by the time you try it :shrug:
