Glad 1.0.1 got you past the Icefall! Room 14, the Cinder Bridge, is a sneaky one: the cracked floor is a bridge over lava, and it falls away a moment after anyone steps on it. So if one dwarf crosses alone, the other two are stuck on the wrong side (R restarts the room). Clear the goblins first (Eitri charges the near one, Brokk shoots the one that comes over the bridge), then pick Dvalin with SPACE, press F so the other two follow him, and walk right across without stopping. The password CIND takes you straight there. Version 1.0.2 is up too: the lava now shows under the bridge, and the room's card says to cross together. If it's the fire jets of room 15 (the Furnace) instead: they burn for a second and rest for a second, so go just as one goes out; with F the others wait before each jet. Good luck, and thanks for sticking with it!
