Isn't this what this is though? There are certain builds where if you follow them to a T, then the game is "easy" and you win almost always. If you just experiment then yeah you can win by some crazy stroke of luck, but most likely you will just have a bad time.
I had the same experience in Caves of Qud(which is great btw) - there are some builds that really really really work, and others which are unwinnable.
