I love the art work! And I like the concept you've built with controlling the map generation, it was also a cool surprise when the eagle devoured one of the rooms lol. Unfortunately he wiped me out and then I didn't get to see him again. I kept building rooms but I got to the point where my only options were rooms with more enemies. I might have run into a glitch so I may try again later to see if I can get further in the game. The transition when going up through a doorway could also benefit with some initial horizontal movement when you enter so the character doesn't fall right back down to the room they came from.
Very fun concept with controlling the map generation! Would love to see you expand on it some more! Plus the art work is very soothing lol.
