Hello again!
So, I've reclaimed the 15-digit code and yeah, you can basically brute-force each encounter by having enough endurance and attack. I did it with all the enemies, and the bosses (Vampirelle, Goonther, and the secret one). Also, I think I've encountered a bug with the secret boss: after a couple of hits it slowed me and then never did damage to me again, so I was able to breeze through it.
I'm aware of the T key for showing some info, but I'm talking more about a toggle on / toggle off kind of thing, rather than the 3-4 seconds then disappearing that you have in now. It's a minor thing, just a QoL thing for some players (but it's okay either way!).
