right on, forest is a toughie because we still have fun with the forest and also want new players to have fun too. it's important for experts to enjoy the forest in certain ways even if they are playing a more "maximize efficiency" game. so that's one reason pink spiders are in there, esp now with the recent economy changes.
re: the random start room. i'd love this too, but it's tough because we feel it would incentivize quick restarts to re-roll until you got what you wanted. exploring powers/mechanics is something we really need to find a way to offer. right now we're talking about extending the height of the crystal/random rooms and throwing some dummies up above with a few preplanted versions of each suit offered to be able to practice in that way.
