I'm not sure yet I consider the game finished. I'll release an update when I find some time to fix some bugs and add the final ritual animations to the gallery. But when it comes to actual content, this is something I'll think about >)
That's strange. This should be fixed in the last version. Do you remember the last thing you did before triggering the bug ? Did you went in the gallery before maybe ?
I'll think about adding stuff in the game in the future, but indeed, adding a mini-game can be quite complicated. As a matter of fact, one of the reasons why the game was "delayed" for two months was because I wanted to add the Kuraksa easter-egg >)
The Black Eyes event is an easter-egg you can find by replaying the maze nightmare in the gallery. There's an action you have to repeat multiple times to activate the secret >) .
The gallery will automatically unlock after you have completed both rituals a certain number of times. However, you must have viewed an event once to view it again in the gallery.
This is a false positive. The game is safe. That being said, the fact that this triggered an anti-virus is strange as it's just a simple Unity game. I'll look into it.
Sadly no. This was for another game that is currently on hold for various reasons, and I chose not to add this option in Purification Process for now as it led to other unexpected complications.
