Hi, thanks for your review!
About Chris. In the latest version, I will add about Chris arriving at Haunt for day 2. The branch with Chris was meant to be secret and is mentioned in the main story to make his presence known.
In order to use the tincture bottle, you need to meet some requirements on the lust parameter (you can find out more on our website with the walkthrough for Day 7)
Aiden is present in the game as a minor character. Interaction with him is not planned. But in the sequel there will be more history about this character.
Day 7 is not the final day of the game, day 8 will appear after the update with day 7 of Chris. On Day 8, we'll say goodbye to our friends. At the moment day 8 is still in development.
I will think about the markings on the map, but they will probably only appear in the sequel.
Some of the places on the map, which I left as a bookmark for the future were not useful for the final version of the game, and most likely these places will be removed from the final version of the game.
