It is surely one of the most suggestive games in this jam. How the story is narrated, the atmosphere and the visuals all add to each other. Also the presence of optional collectibles and the fact that they serve a function really gives me that GAME feel.
It's really a shame that the game is so heavy, because i think that, otherwise, many more people would have tried it and enjoyed it, but it wasn't easy to make smaller.
There are a few things I'd improve: the camera sometimes plays against you, especially when you are coming back from one of the 3 zones. Maybe you could let the player have some control over the camera with the mouse.
In the ending, an option to exit the game other than alt+f4 would have been nice
