At the moment, if feels as if standalone quests that rely upon standard "platform game" skills -- particularly accurate jumping -- are a crapshoot depending upon server responsiveness, because you can't judge your position and that of any in-game elements with any real-time certainty. Since many of those quests (Rook's Egg, for instance) can be fairly hazardous to energy and mood, it's pretty annoying to be lagged to death by them, so I'm basically avoiding them right now, and it makes me unsure whether they'll work well in the final game. Perhaps it might be better to make those standalones more puzzle-like and less Mario/Sonic?
