I like games that talk about game design. Especially in a game jam, where most people playing the game will likely also be game devs, that makes a lot of sense.
This is a nice implmentation of the "create the dungeon for the player" idea, that quite a few entries went with, but it goes further than most by asking the player to actually provide stat values for the foes and the twist of optimize the dungeon from a dev perspective works well.
10ish endings is quite ambitious for a jam game, especially a solo project.
Great entry, I hope you got some sleep after working on this for 44 hours straight!
Cheers.
