I had a bug in my first fight. After one hit, everything froze. Moreover, I did not expect a fight, because nothing happened when encountering ghosts on the street.
I restarted the game. The second time, I couldn't get past the second floor because of the ghost stuck in the passage, which I couldn't interact with in any way. I opened all the chests before that and interacted with the characters.
Sadly.
This game looks beautiful.
And there's also a mouse control. Working character stats. Saving works.
