A Good Game! You took this gamejam very seriously and I am impressed with how much this game offers in a short timeframe.
In terms of the story (wish I could add spoiler tags on itch lol), I didn't understand why the animals had to be mean to the protagonist at the start. It makes sense that the capybara wants to vibe with the animals and the animals though he would die if they didn't stop him from being too friendly, but that would work better in the middle of the story than the beginning imo. I think it would be stronger if losing the mother happened during the gameplay. Perhaps you get to play all the minigames the first time with positive feedback, then that happens and they don't want you to help because the mother being captured teaches them that generosity is dangerous. It's only until you are rejected by all the animals do you find the human to help, which leads to the positive ending.
I realize the story can't be too long, but that scenario would connect with me a little better. The current scenario would make sense if you put more emphasis on deciphering clues about what happened (like the scarf). What do you think?
