I noted that you wanted to talk about adding possible game mechanics. I think it'd be neat if you added larger almost arena like areas and "bosses" either making the game darksouls ish or a fast paced shooter. I do also want to say I wish you could go further down and up, maybe 5 layers down, 5 layers up that are reliable then after that it becomes a bit less likely to find rooms the further down or up you go?
