I do think there are several things I want to mention in the review, but that is what reviews are for, so I will mention them. I think just submitting a game is awesome, so please take this more as feedback than anything else.
Visually, the game uses the default RPG Maker assets and default sounds, so I cannot really rate it high in that area since it essentially reuses assets that can be found in many other default RPG Maker games. For that reason, and because a lot of people in the jam are creating their own assets within the seven-day time limit, I cannot rate it very high. I also think there are some odd tile choices in the house. The tile used for the doors looks strange to me because it never fills out, and for a mansion like this, it does not fit since it looks more like a door at a bar or something similar. The main character also looks like they came straight out of a fantasy game. The sound is a bit loud too. I think it should be set to around 40 to 50 percent by default.
More importantly, since none of the visuals are unique, which is fine, I think more attention could have been given to the writing. Sometimes words that should be capitalized are not. The word "Though" is sometimes written as "Tho," which is fine as slang, but it feels immersion-breaking for a game that focuses mainly on its story. There are also mistakes like "Dear" being misspelled as "Deer" and cases where "seem" is used instead of "seems." This is important because, as I mentioned, you are using the default RPG Maker packs, which means the story needs to elevate the experience. However, when the writing has many grammatical mistakes, it disrupts the reading experience for the player.
As for the story itself, I do appreciate that it is a legitimate horror story. However, I think there is a lack of setup. For example, we get flashbacks with the character’s mother, which establishes some things, then we explore, find a picture, and after burning it, we are told to sleep. I do not think it makes much sense for the character to want to sleep in the house, especially since the bed has blood on it. You could have easily just said enough time has passed that it is night time. Still, I think it has some charm. It reads like one of those slightly campy horror movies. Especially the ending.
Another nice thing is that it has dialogue for many objects, which is very cool. I think there is a lot of room for improvement, but the fact that you submitted a game to a jam means you have already succeeded in many ways.
