I like that you can just change the content of the dungeon.
But it feels like there should be twist about. For now if you need HP - select HP. When you full - select traps.
The idea is original but I want something about it to be difficult or so you need to scarifies something. Or at least - before each level - you choose what it will contain and you can't change it until the end of the level or something like this.
The vibe is nice though )
