Thats fine - I just think that this game won't be able to break any barriers like stardew valley did - stardew valley was a broad, all-encompassing field that included things such as digging, farming, etc.
Those were just ideas to do if you were open to the consideration.
If you want to keep it going in this direction, I would still recommend tailoring those sorts of features (ignoring the battler part), as it could be fairly interesting and allow you to stand out - the idea of customizing pets/"creatures" through the necromancy of dinosaur fossils.
