Thanks for the comment about the music, I found them on open game art. You have to water the ground several times. There is a small 1 second delay between when it is watered and when the tree grows.  I'll try to add some particles for the water splash. Once I get more content done, the plants will grow daily instead. The final game will have several areas, each with a different track. It might take a couple weeks for the next update. I'm adding a bit each day, but I'll be waiting until after both jams I've entered finish voting to update.
