Today I'm working on 'switch' doors - wherein you walk onto a floor symbol and one or more doors open. Once you step on the symbol, the map 'tours' over to each door and shows them opening. The symbol fizzles and shines. It's a pretty cool mechanic because it allows all sorts of nifty puzzly things. The end goal of every quest is to locate some special relic (well, most of the time). So this door mechanic (plus teleporters, darkness, locks, plot pieces, monsters, spells, magic items and more) guides you along the quest piece by piece. Hopefull I'll get the switch doors finished this weekend. Things are really moving along quite well - very, very satisfying!
