Very nice little game here! Not much to say about the gameplay, it's fairly simple and clearly isn't the main focus, I'll just point out that the collision with the trees is kind of off, like I can't go underneath one with the way your character's collision is handled. But that's fine.
From a narrative perspective I'll say that it's a bit of a missed opportunity that there aren't alternate paths depending on what you do, as it really feels like that's what the game wants to be. It feels like if I don't speak with the sheep, it shouldn't die on day three, and if I go back to the house on day 4 maybe I just die?
But I tried that on a second playthrough and it didn't happen. If you wanted to add those and didn't have time that's obviously perfectly understandable, but if you hadn't considered that maybe it's something to consider! And also in that vein, possibly make more things in the farm give you hints about what happened, though that is more for if you wanted to make a longer version of this game.
Thanks for sharing, hope you had fun!
