Really liked the dark city with the creepy people around and also the cameos from other YouTubers! Really added to the personality of the game and the in game world.
Though I think adding more characters, not necessarily voice acted; just more people in this small part of the city who each have their own personalities and dialogues would really make this an enthralling place rather than a narratively straight driven story, I think you did well with what was there!
Also maybe would have liked to see more of a reason why the demon dude popped up and the scary looking creature starts chasing you as that happened nowhere prior and seemed random to the story, they were still pretty scary and effectively used! Well done with the game and great job bringing YouTubers in for voice acting for it, and good luck for future games!
