Been enjoying the game a lot, but I wonder if it might be worth to try to add some 'cause and effect'/longer term events to the game.
A lot of events currently feel like they are very 'It happens to you for a bit and then is done' style. Stuff like the super heavy fog, red sky and such is cool and atmospheric, but it can eventually feel like when an event happens, you know it is a one-off thing that will be gone after it did what it wanted to do. Kind of hard to explain, but I guess they have a sort of disjointed feel, which is natural due to how the (non-story) events work.
Random thought I had to deal with this would be to maybe have 'sub events' and such. Like an event could spawn a ~spooky~ item on the map, and as long as it is around, other things can pop up. Like some alien artifact that causes weird shit to pop up intermittently around the map, not super frequently but enough to make a player wonder what's up until they finally go investigate the weird dot on the radar. Or an entity that needs to be engaged in some way or events will keep happening (There is that deer related one which is already a pretty good example). Basically stuff that makes the events feel more connected, even if they don't necessarily all are.
Of course, this is way easier said than done and this is mostly from the perspective of someone who spent way too many hours playing this game already. Not to mention that with horror, making cause and effect too clear can also take some of the mystery out so even if such events were added, figuring out the fine line between giving the player clues on what causes what, without removing the dread of uncertainty is a difficult task. So uh... good luck with that, lol
