Check my itch.io page where I'm hoarding all of the possible alterniteves to Adastra and FBTW there are on itch.io, you might find something that fits to your tastes!
hmm I would recommend "Roads yet traveled" by CryptidDog. Um you end up in space in another galaxy and There are 3 dogs you end up working with eventually. and "Wayfinder" by Lavan. in this one you encounter 3 wolves and depending on which one you pick you do travel to another world but the method involves dreaming.
