This was such a wierd experience, in a positive way. I could feel the tension from the moment I interacted with the mirror, then I found the chest and the Mettaton music from Undertale started. I was confused for a few seconds, took that funny break and then went back to the horror. The jumpscares started, and they were super effective with good sound design, which a good horror fan knows is way more important than graphics, and this whole game is a good example of that. The music felt right, even though it could loop way better, but I discovered a bug with it; when time runs out and the game over screen appears, if I decided to restart from the current night, the music would overlap, and it was so annoying that I had to restart the game twice (I played 2 runs) in the web version. You can easely fix it making the music stop at the game over screen. Now speaking about the controls, they felt sometimes smooth, sometimes clunky, especially in the examination and dialogue parts. So, at the end of the day, this game does the most important things well: it truly is an horror and that is something impressive for a game made in 7 days. It just needs to be a bit more polished and most importantly that music bug needs to be fixed, that's the only complaint I personally have since it's frustrating to have to restart the whole run. I don't know if others just turned the volume off to overcome this, but I refuse to do that, especially in an horror, where sound is 90% of the game. Interesting idea and overall good job.

Impressive setup and good interpretation of the theme. The entire house is well thought out and the overall design is really good with maybe the exception that the rooms are a little to big.

Others already pointed out the issues with the dialog and collisions but that did really bother me that much.

I like the moments where the ghost randomly moves across the room! I'm horrible with horror games so definitely spooked me. Also liked the idea of finding all the necessary items to keep progressing and the overall story behind it all! Some things to consider:

The collisions for some of the objects felt a little big and make it a bit hard to move around. As someone mentioned, dialogue can end up stacked on top of each other at times. Also I think dialogue could use enter key instead of clicking the button since closing the dialogue felt unresponsive at times. I also got stuck at one point since I had no idea which room the items were in or where to go but I just got too creeped out by this spooky atmosphere so  it definitely did its job!

Overall a nice submission and a great start for a game! You should definitely keep working on it after the jam!
