I've learned some more scripting features recently and I've just integrated them into the game. Namely, making backgrounds have layers, zooming in or out on backgrounds to simulate movement, and making backgrounds bounce to simulate riding on/in something. 

I'm very excited over what this has done to liven up the game. I'm trying to make the movements subtle so no one gets motion sickness looking at it (especially me!). I'll be exploring these features more in the future!
