Hi! I absolutely adored this game myself and it's become one of my all-time favourites!
While I haven't played a lot of games exactly like this one, there are a few aspects that reminded me of other games, so I hope these might work for you!
The whole time while I played it, I kept thinking it felt like a mix of Animal Crossing and Night in The Woods. I've never played Animal Crossing myself, but I've seen and heard a lot from it and it gave me very strong vibes. Cute animals you can interact with, a little island where you can fish and collect things, peaceful with no enemies, etc.
It reminded me of Night In The Woods in the way the characters interact with you and speak: really witty, funny, charming and heartfelt conversations, with a very similar flow of speech bubbles that feel like a very natural conversation. Additionally, the characters in Night In The Woods are all cute little animals like these, in a similar art style. Claire actually reminds me of the main character, Mae. The game also has a very cute, simplified art style with a lot of warm tones and forests! The game is certainly darker than this one, more existential and there's a bit of mystery, but the dialogue and characters in Night In The Woods are such a delight and I highly recommend it!
The art style and the vibe also reminded me of Life is Strange. Although Life is Strange is a much longer game, and it's got a more realistic style, it is a very relaxing game with opportunities to get to know the characters, sit down and enjoy the environments, a relaxing soundtrack and very lovable characters. This game is definitely darker and very emotional, but the art style is beautiful and it's my go-to relaxation game. And the story and characters are amazing.
I think you'd also enjoy Firewatch - it's a first person narrative game where you play as someone who has just become a firewatch. You basically explore a beautiful forest, with a very warm and colourful style. I'd recommend it a lot if you enjoyed this game, it's got beautiful visuals, it's very relaxing and there's also a lot of witty dialogue (still - there is mystery and danger in some parts, so not as harmless and innocent as A Short Hike).
I hope any of these suggestions will come in handy! ^-^
