I had the same experience.
Up to room 46, it felt like every failed run built up to your eventual success, like any good roguelite. You failed, but at least gained a bit of knowledge, a permanent upgrade or improvement to the state.
Then you get to a point where each run is less and less rewarding and eventually give up. There’s nothing left to learn or upgrade, it’s now a fight with the RNG.
I still have it installed and I plan to keep it until my smartphone stops working
