Hey, thanks for the video. :D Watching you and any potential bugs you encountered was helpful. The small lag spots you had did bother me so I will have to look into that for next time. As for bugging Marina, a few people have managed to glitch her here and there although the location you did it in was new to me. lol
As for the guide part, I actually did want to but I've had some build issues for a while so I was unable to directly fix and add more info in game. Adding tips to the game page was best I could do in the meantime. :/
And yes. While it's not super story driven, there is a lot of stuff here and there giving you an idea of what's happened in this house. Most are hidden in books, others in secrets find through out the house (you missed a rather spooky one when reading the girl's diary). Admittedly, it's not easy to find/notice them if Marina is busy chasing you. lol The voice in particular is related to two endings as well. If you ever decide to play again, look around that room more. Specifically the banner. ;3
Also, I'm already subscribed even before you made the video. ;3
