Ah ok, I misunderstood what the doors did. I'd assumed that there were floors because the shrine messages talked about blessings lasting for the current floor.

I think it would help the agency if you had the ability to walk around to rooms of your choice (n-w-s-e and the like). Maybe have the ability to listen at doors to help guess as to what might be inside the next room...

Also, if you can go back to rooms you've already cleared, you can rest up and heal your wounds or whatever.

You could also make it so that after awhile, rooms you had cleared are no longer clear anymore as wandering monsters have arrived - or maybe there's a small chance that a monster arrived right as soon as you left the room. Probably easiest to just calculate a small chance of repop of cleared rooms after every player move.

When you flee, you are panicking and go in a random direction (or maybe you fail to flee). So fleeing could bring you back to an already cleared room, or run you into another room with an even worse monster...

Perhaps some "elite" monsters can sometimes follow you when you flee? So then you have to keep fleeing until they (maybe) give up the chase...

You could also add an ability for a "knight" class called "retreat", whereby you can choose the direction you flee (with a low but random chance that you panic)...

I didn't see any way to level up your companion, or any special abilities other than attacking along with you. Giving them abilities that they use semi-randomly might help add a new dynamic to the game. Maybe some companions are clumsy, or they are usually powerful allies but sometimes play tricks on you. Or they abandon you if you panic, and you must go find them.

You could add stamina dynamics. For example: a knight has heavy equipment, so he tires a lot and must rest. A rogue, on the other hand, is light on his feet and can go long distances without rest.
