Well, I think my gardening game is about half to three-quarters of the way done with the real coding. I can load and save a garden (inelegantly, but it works), take pictures of the garden, plant flowers in the garden, and various native wildlife will come and visit the garden. I think it's cool. I ended up using GameMaker, some free software for quick and lazy game development. It's a great program and can do as much as you need it to. I ended up registering it because it was so useful.
I still need to come up with a clever name for the program, put together all the acknowledgements for the images and sounds I used, create some more flowers, and basically polish it.
I have great fun making little gardens with it.
