That’s a really cute idea! I like the overall feel of the game, sound effects, and somehow visually it makes me feel a bit nostalgic. Like something about it is so “retro”. The assets you used are cute but as they are not yours I can’t really rate them. However, I’d say the choice of gray colour for where UI is located - I am not a fan of, would love to see something more colourful :)
Also, the naming of stats doesn’t feel quite right: as Hunger rises with food, it should be renamed sth like Satiety, same with Boredom, it seems the full bar means my otter is not bored at all, and if so, this stat has to be renamed as well. Thirst was also rising when drinking, which is counter intuitive as well. I feel like simple re-naming of the stats would help, otherwise you would need to change the mechanic and make these bars decrease instead.
I liked the mini-game with catching fishies, it was simple and cute. Do I understand correctly that it is endless? As I could stop it only by changing the activity.
Overall, sweet and relaxing game, good entry for a jam ^^
