Thanks for the game!
There are many points that can be improved and I thrust you will improve the dungeon, breeding and goals, but one point in particular spoiled my experience: the Stamina refilling on level-up. If you invest in Int and Stamina you can level-up multiple times in a day, granting more Stamina to level-up again. Each time you have to exit the room, level-up and enter the room again to resume.
