Soflocking bug: if you lose to the boss not only the boss fight restart immediately, but once it's game over, you can't return to the boss because you no longer have the cell key.
Also, why did you remove the save functions? the whole prologue is a bit annoying to redo
The merchant is the save spot, so it's not removed
Sorry, I didn't see
All good. I just need to clarify it better
