The updates look great. I think the trees are new too? I was thinking that you could have levels - but that would kind of defeat the purpose of the infinite drive. What if you had a toggle switch for day mode versus night mode. You can toggle it mid-game just like changing cars. The track never changes it just make it night. I don't know how you're doing the background so I'm not sure if that is even possible. Just an idea! Also, I'm not sure I like the music. I like the retro vibe of it - it fits the game - but perhaps there could be options here too?
