Are there more monsters or more enemies planned for this game?
Like dragons, mages, thieves? Or having enemy AI that retreats when getting injured, which accumulates the threat of the next wave?
This game is fun when its short and frantic, but so far the builds are pretty the same since the enemy component is the same all the time.
I suggest more variables to increase replayability? For example, at every playthrough, the types of enemies appear and don't appear are always different. Same goes to rooms, sometimes you get different monster rooms instead of lizard room.
