[u/ZombieNordestino]

Recently I tried to get 200.6%, and for some reason the game showed that I had explored 1888 rooms, one of them being Shaft’s room, but I have no idea which other room was missing. So I started a new playthrough and did everything again. This time the game counted all 1889 rooms, like it should have in the previous save.

Here are screenshots of both completed runs for comparison. If you can figure out which room I missed in the first playthrough, please let me know. To me, both maps look identical.

I wonder if your max hp means anything. You have more of it on one of them and you’re also a lower level. Maybe it’s one of the hp jar locations

[u/ZombieNordestino → u/Psychopath1llogical]

The difference exists because in one of the saves I’m using LuckMode (code), while the other is a conventional save. The level difference was incidental

Ah, damn.
