Pros and cons are down below) Check my vid out here (likes and subs are highly appreciated)):
Advantages:
1. The game is so spooky! Well done! I enjoyed every scare the game had and it surprised me a lot. I feel like even if the concept of "going into the same room that changes a bit" isn't new, you managed to make the game look fresh nonetheless. Very cool!
2. The storytelling is amazing. I love how you give hints to the player but it's up to them to decide what has actually happened.
3. The secrets! Yay! The fact that this game had secrets hidden everywhere made me replay the game. That means that you did a nice job of making the player want to know more and try again. Moreover, the secrets were kind of cool. And the fact that there are different endings is also awesome. (I put it here because I feel that you need to collect secrets to get the other ending but I might be wrong and it might have been a total coincidence for me))
Disadvantages:
1. The lack of background music! Any non-intrusive music would be better than the lack of music. I know that it's kinda hard to choose fitting music but I feel that it's still a "must-have". If you intentionally made the game silent then you could add the "sound of silence" - a wind behind the window or neighbors walking upstairs or the floor creaking to make the ambiance stronger. Or even better - make the radio play a non-intrusive non-copyrighted song that can be turned off if the player wants to experience the game in total silence.
2. The face in the darkness. It is an incredible spook, don't get me wrong. But it doesn't fit the game whatsoever. I guess the style of it reminded me of some creepypastas and stuff like that and it felt completely out of place. I would suggest replacing it with something more subtle, not so "in your face". Here's my suggestion that might inspire you: make the player go inside a dark room, close the door behind them so they will stay in (almost) complete darkness, then make the face (normal-sized face) appear (maybe with a sound cue to attract palyer's attention), and after they approach it, then continue with your sequence. That way players would have no chance of missing this great spook but it wouldn't fall out of the whole picture at the same time being too bright and distorted.
Overall:
I rate this game 4.6 fire axes out of 5 (officially 5 in the rate section). This is an incredible game with great spooks. It's fun to replay and to investigate more thoroughly. But it could be so much better if some minor details would get polished. Can't wait to see more from you! Stay awesome, devs!
Hope my feedback was useful!
*btw played your game called Lights out before and I wanted to say that this game is so much better! It's very cool to see you grow as (a) developer(s)!
