I think a room - by - room dungeon with individual baddy types would be cool in this regard. Have it randomized every 24 hours to include or exclude specific rooms... only 10-20 possibilities. Players who died inside would be warped back to the start. Maybe make it cost 100 or 200 gralats to try, and the prize to get through the fastest of the day could be 1000 gralats or something? Maybe a seasonal 'fastest times' leaderboard?
