The presentation and story telling in this is actually beautiful, like it's a really simple story but it still moved me which is something I would never expect from a game made in three days and the desolate and bleak atmosphere fits well with it.
A minor nitpick I have with the game play is that I wished movement inputs were buffered, it feels frustrating to press a button to quickly move out the way of a seal only for the input to get eaten and then the seal to hit you.
But other than that the quality of this is incredibly impressive for the time scale
