Feels like there an option for 1920x1080. Walking around should have diagonal movement. Collision doesn't have the correctional sliding that's common to games in this perspective (does Gamemaker not come with this physics feature?). I don't like the sound effects for examining things. I get it's trying to be quirky, but there should really be more context when you start the game (e.g., who are you?). Having so many identical/pointless environmental descriptions is a waste of the player's time. If you examine something, it should be worthwhile. There should be a run button. I don't like using asterisks to describe actions. Saying words should use quotation marks, while descriptions of actions should be plain text. The rock puzzle was not good, as there were no hints nor reason to think examining the rocks later would be different than earlier.
The overall idea behind this isn't bad, but the execution is unimpressive. The artstyle generally works, but these types of character-focused games benefit from detailed/expressive character art. See: Omori. None of your characters have facial expressions. The writing relies too much on the player being familiar with this genre, making characters behave more like aliens than people. Compare the writing to something like Your Turn to Die. Despite the premise sounding interesting on the surface, it has no hook in practice. Being lost in the mountains was done interestingly in Remember11. From the little that is present here, you don't seem to be a very good writer. My favorite part was actually the character portraits, despite them being unexpressive.
