Visual style is great, all the animations bring life to the cutscenes, great job there! The two puzzles might have been better of spread out throughout the game instead of having both at once, but they were easy enough to solve.
Regarding the overall difficulty of the game, I honestly found it much easier than Out Of The Stacks, your last submission to these game jams. I think it's fine as-is. The problems the others had with the birds might be caused by them not realizing that you can crouch? Because they are pretty simple to avoid like that. Maybe when you get to the first tree with the crows, you could have a floating text momentarily appear that says something like "hold down arrow to crouch". Just so that the players are aware of that ability.
The story is somewhat confusing, it almost seems like there's some middle part of the story missing and you go right from the beginning to the ending. At first, the mystery is set up, then you play a short "dream level" and then the mystery is not only resolved, but the main character apparently knew the answer all along and actually did something off-screen to take care of the problem without the player's knowledge. It's just so sudden and it seems like the game was originally supposed to be longer.
It was also very short, could use another level or two, but the fact that I wanted more speaks to the fact that what was there was very enjoyable.
Great job!
