Dungeon Developer (http://www.kongregate.com/games/nerdook/dungeon-developer?acomplete=dungeon) is a flash game where your goal is to lead adventurers higher and higher in your dungeon. there are 15 floor which you can map almost entirely by yourself, except monsters, traps and power-ups that are already set when you get the floor.
It's really fun to have those adventurers try to explore your dungeon until the final boss.
There are medals depending on how fast you can have the adventurers to finish it.
I've done it, on my first try, on 24 days which gave me the platinum medal :p
