Pros and cons are down below) Check out my vid here (likes and subs are highly appreciated)):
Advantages:
1. I liked the anbiance a lot. The environment was really immersive and I liked how some details also were telling the story of the house.
2. I enjoyed voice acting a lot. I think it added a lot to the game and was a very nice surprise in general.
3. The game actually scared me which is a sign of a good horror game.
Disadvantages:
1. The puzzles were too simple for my liking. Maybe it would be nice to add something a bit more difficult in the full version of the game. But not too difficult, of course. It's hard to fing a perfect balance, but I'm sure you can do it!
2. I wish there would be more notes explaining the story in the full game. Also, I'm very curious who would leave a missing person posters near abondoned haunted house even if it's the place a person dissapeared. Nobody would see these posters anyway. It didn't really make sense for me. Maybe it would be better if the main character would have the poster right off the bat?
3. I think the game would benefit a lot from adding more random ambient sound cues. I guess that would make the whole place way more creepier. I was expecing to hear someone walking upstairs or breathing into the ear or something like that. If that makes sense considering the story in the full game, of course.
Overall:
That was great. I enjoyed the game a lot and I rate it 5/5 stars. Can't wait to see the full version! Keep up the great work!
Hope my feedback was useful!
