I agree with most of the other posts regarding the directionless gameplay. Although that might be a good idea for other genres of games, a survival/horror game tends to do rather poorly with that kind of focus. Even the early Silent Hill games gave some indication as to where the player was meant to progress to by allowing players access to places they haven't yet explored as they continued to play through the game.
This game had a point, albeit obscure, and a sort of philosophical message when the player finishes the good ending, but only after a great deal of digging into the comments to determine exactly what is supposed to be done. Fortunately, due to boredom, it didn't take long for me to figure out that killing yourself is a prerequisite for the other two endings.
It would have been nice for the player to have a sort of "suicide run" area to explore, which would have killed the player, but allowed them access to certain storyline elements that they wouldn't be able to reach if they just played it safe. For any good horror game, one of the most horrifying areas that can be made are areas that ensure the that the player is in a vulnerable position, gameplay-wise, without making it frustratingly difficult to traverse, like Silent Hill 2's Hotel elevator, where you're required to drop all of your items and weapons before proceeding into a monster-infested area. Forcing the player to retreat into their house every day adds a decent amount of urgency, but at some point, doing that every day becomes a Harvest Moon-esque routine, and players quickly tire of it.
Also, one of the majorly important aspects of any game that depends on story is spelling and grammar. This game would have gotten at least 4/5, but the intro completely killed the mood. Also, any sense of foreboding or mystery associated with the Visitor was completely thrown out the window throughout the encounters. I would highly suggest you team up with a good English-speaking editor or writer.
Overall, I'd rate this game as being pretty meh. Some good ideas going, but there are occasional game-breaking bugs and the implementation could use some work. Looking forward to a sequel with better gameplay, though.
