I really like this!! The game has a very charming humor that came through with the narration and end screen messages. I'm not sure if this was intentional or caused from an error, but my game closed after dying to the shark in the first section. If that's a bug, then ignore this haha, but do be careful with closing the game intentionally, it can be frustrating if it happens to often and seemingly for nothing significant and the player might feel punished. I would also suggest in the spear section that you either give the player more than three spears, or resetting the level as soon as they miss one. I had to play the section a few times, and what ended up happening a lot was I would already have missed a spear and would have to wait out the whole sequence until the end when you reach the shark.
Very nice!! I adored the short story. Congrats on a successful first jam :D
