I hadn't thought to check until you mentioned it just now, but yeah, Quartz Charm is actually adding more damage than Scourge/Tupsimati now, at least checking Tenshi. About 6-7% more damage for her at level 1,123, ATK is at 1,830,082 with Quartz Charm and 2,001,418 with Scourge. Yeesh, Scourge doesn't even add 10% more ATK at this point.
Anyway, yeah, there are
, along with the two achievements that can be seen but not acquired. One is clearly for

Though, confusingly, the unlock condition is
In addition to the visible achievements and the files in the game, from the remaining unattainable item names, there's
For the 1.104 update, 3peso scaled the Corridor leveling rate down from 36 levels every 10 floors (or 3.6 levels every floor) to 34.5 (or 3.45 levels). This affected the entire Corridor, both the old and the new bosses. It's possible that in the 1.105 update, 3peso will scale the leveling rate down again. With 250f being 1,092 for the boss and the current leveling rate of 34.5, the 512f Corridor achievement will see enemy levels at around 1,995. Accounting only for additional Touhou bosses, the levels will be in the 2,200 range at the very end. Except for the Touhou bosses, all enemies are listed with a number associated with their floor number, even bosses, Corridor enemies begin with 99. This regrettably doesn't help any with determining the length of the Corridor because 99 is being used to refer to there being many floors, fitting for the "Infinite" Corridor. I would wager the Corridor ends at 999f or 1000f and eternally loops like it did on 101f and 251f, with a random boss at the end. If that's correct, then with the current leveling rate, 1000f would be level 3,679. Incidentally, Corridor enemies are further divided by numbers.
This is more a trivia thing, but on 29f,
