Thanks for playing.
So about the enemies, I think we communicated it poorly but the whole premise of the game is that all enemies were defeated, all puzzles solved, and all doors already in respective locks. Your job as a janitor is to put everything back in place and lure new monsters in (by adjusting the liquid and amount of torches in "potential monster lairs"), so the goal is to rewind the dungeon back to it's state like it was when the heroes first entered.
You don't see any enemies in the game, just prepare the lairs for them.
Yea, collisions on the bridge were a little tricky, looks like I didn't test it enough.
Hope that clears things up.
Cheers
