This is a wonderful game. I like the music, the art, and the gameplay. My only feedback is that the soil keeps fertilizing on the same few horizontal tiles and I'm not sure how to make it fertilize downward, so maybe you could make it a little clearer to the player. Overall, it's good, and it blends really well with the theme of "death is a new opportunity."
Edit: Figured it out. It's very fun. I recovered the gem in 163 days
