A truly lovely, super charming little game <3.
I only had one issue with the game, and it was when you planted seeds, or put your water thingy right on top of the place where the seeds can be purchased. That stops you from either picking your plants up, or the water thingy. I had to restart the game the first time I tried the game.
If you keep working on this, add some level progression. This is already addicting enough as it is, so a little something more will definitely scratch that harvesting itch haha. Your kid should be proud he's dad is this awesome.
