go full maximalist!! fill that baby with cozy nature vibes. if you feel like designing and drawing more UI elements, that is.
marketing-wise early next year might be the best time to release the game, since it's set in spring and chock full of those aforementioned cozy vibes. or you could release it on itch this year then on steam early next year- you'd probably get some repeat customers, folks who got it on itch, loved it, and want to replay it but earn achievements this time. but that's just my two cents, it's your game and you gotta do what you think is best.
