Anything works, just wish it felt bigger (ie more variation), as it currently is I think I walked around about 7-8 minutes before realizing that it was looping. If you're actually planning on expanding, maybe some more 'room's, like the one with the TV in it, densely packed with furniture and junk etc.
I've been playing this for 10-30 minutes nearly every day since I found it, researched Kowloon history, read a photobook on it, watched a couple documentaries, fascinating, and very good work dev. Do you intend to keep working on it? I don't know any 3d modeling if I did I would definitely assist. Let me know if I can help in any other way.
