I love your interpretation of the theme. The concept of creating your own route through the dungeon works really well, and it is unlike anything I've seen before. The use of the doors for combat was also really creative, and it was surprisingly deep. The enemy variety also complemented the combat quite well. However, it would be nice to have a bit more range on the door spawning, as I found it difficult at times to get close to the enemies. It would also be nice to feel less invincible, like starting with less health and getting pickups or something. Overall, I really liked the game and had a lot of fun. Well done!
