What a charming, beautiful, and soothing game!
I absolutely love the pixel art, the vibes™, and the space you've created for the little rock to roam. I also think the character design is wonderful.
You did a great job on this submission and your style, ability to market / make an appealing page for your game is top tier. A few quality of life improvements that may improve the game (in my opinion) - the ability to plant when stationary potentially for precise gardening and the ability to walk on a diagonal?
Again, great job and looking forward to seeing what you come up with next :)
