Alright so I gave this one a good try, and played it for about two hours and a half (I had to replay the beginning because I had to go get lunch and there's no save files, which is pretty normal for a game made for such a short jam).
There's a lot of good things, and some that need some polish. I hope you don't mind the review, I'll delete it if you feel like I'm being too harsh. I just think it has potential and so I'm taking the time to point out what (in my opinion, someone could have a different take on it) needs a touch up.
The maze with its slowly disintegrating texture and architecture as a metaphor for the protagonist sanity is a great idea.
However, I got lost for like half an hour in the first map, because the corridors are all very non descript and the pure white walls, ground, and fog make it very very hard to tell them apart. Maybe adding more "misplaced" items like the clock would help, or reducing the fog?
I was really hype the second time I got to the maze and there were the missing textures. I really did feel like the environment was breaking down around me. And it made navigating the maze a lot easier, as I could use those to know where I was. Plus it really gave a "glitching/falling apart" vaporwave vibe to the map which was unique and stricking.
I am not sure I understand why there were random dead soldiers on the ground however, and the registered message starting with a "I fucked your mom" joke kinda killed the mysterious/spooky ambiance.
Also nothing makes it clear WHY you need to press the levers. I mean, as a player, I press buttons because they're there, but I don't know why my character is doing it. Maybe making sure the player sees the locked door at the entrance of the maze and then letting them roam in search of a solution would help make it feel more logical?
The second scene in the flat was the weakest in my opinion, it was a lot less interesting than the maze, despite having more things to do. The VHS tapes is a simple enough way to give players missions, but if there's no image on the TV, an audio tape would have worked as well... Or maybe it was planned to have some video and you ran out of time? One week is a very short game jam, so it makes sense that you can't do everything.
The fact that none of the rooms were locked meant that the very first room I went in was the grandfather's bedroom and I saw his hand poking through the side of the closet, which kinda killed the later jumpscare. Also the dialogue was very strange in that section, I don't think the lines are playing in the correct order...? And the protagonist says he "can't do this to his grandfather" but he "needs the key"... but we don't do anything to the grandfather and there is no key. It felt like random? The subtitles also don't always align with the audio, playing too late, and the music is way louder than the spoken lines which makes them difficult to understand.
Actually the audio seemed to cut off brutally after a while. And while the silence can be spooky, since it did that every time I lingered too long in a map and nothing else happened, it kinda killed the potential scare.
The three friends bedrooms confused me because, well, there's nothing to do, you just wander into their room and then you leave. But you had established in the previous scenes that you needed to do something to exit a room (gather clues or press levers). So I kinda awkwardly hovered around, trying to figure out what I was supposed to do. Maybe having chains on the door that only fall apart once you visited all three rooms or something would make it clearer? Or maybe I'm stupid, lol.
I really liked the minigame with the radio and then finding the coordinates on the map, that was an interesting change of pace. However, then I had to grab a shovel and wander around some more for a ritual. And the navigation problem came up again as I could barely see where I was going and had no idea which direction to go... Maybe a map in that section would help, since we aren't in a maze anymore? So I got lost for about half an hour, trying to find my way... And I clipped through a hill and couldn't find my way back to the map. I gave up at that point as replaying the entire game back to the same scene would have taken me too long.
I don't know what the link between the dead grandpa and the three friends is (I'm guessing the ritual is to bring them back to life?) but as I couldn't finish the game, maybe it's all explained?
I hope this is helpful, as I said I'll delete it if you want me to.
