Cool game! There are a lot of things in it, and the provided context makes you want to explore the dungeon. I love the detail of the dialog boxes, they are neat. Also it seems to me like a very good take on the limitation.
As a constructive critic, I would say that Canaja keeps getting me all the time! Maybe increasing a bit the player velocity would help? In any case, if the player being slow is deliberate, it is also ok. Hard games are usually more satisfying to play with :) All in all, good job!
