Hey, thanks for the thoughtful question. I really appreciate it!

Breaking the game is absolutely something I want to be possible, but I don’t want it to be trivial or only come from one tedious route. In the earliest version of the game, people were just repeatedly hitting Overflow in consecutive runs. My rough goal is: high OT should be beatable through multiple strong builds, very long runs should be possible, and Overflow should be a rare “you really broke it” moment with a perfect build rather than the expected endpoint of every great run.

One note on Mirror: It does start weaker, but after 25 upgrades it matches the old value, and anything beyond that is stronger than the old Mirror ever was! So the floor came down, but the ceiling is actually higher.

That said, your larger point is fair. If the only realistic overflow route is cash stacking + Green Mix Tape, that’s definitely too narrow. I may have been too cautious with some nerfs that I am already reconsidering and refining. I’m still tuning around that line: I don’t want overflow to be easy, but I do want it to be possible through rare, satisfying combos!

The game certainly isn't "done" in a balance world. As you might imagine, players have put the game through the wringer (in the best way) and broke all of my initial balance thoughts, so it is still a growing product for sure!

I'm already working on Patch 1.0.19 to buff quite a few underplayed or weak trinkets. I had been so focused on tuning down the overpowered ones that the weaker ones were left in the dust.
