Are there any plans to include rooms which are difficult or challenging to traverse in some way?
I think the game needs something other than boss fights for a challenge. It would be nice if there were trapped rooms in overlord towers or even ruins that are intentionally challenging to get through.
Perhaps a vertical room that fills with something bad (acid, lava, or whatever) that requires the player to platform fast enough to stay ahead. Maybe there could be an obstacle course that is only wide enough for a bat or a fish and requires getting past timed traps and enemies as well.
With the way some of the towers work these could be used in addition to or perhaps even an alternative to a boss fight, like allowing a player to skip some bosses if he can make it through the furnace without getting cooked. That way, the player won't be stuck doing one or the other just in case maybe their spells don't work well against the boss or they don't have the dash or jump needed to get through the obstacle room.
