I enjoyed this! Maybe make the shortcut back more obvious when you need to walk to the store. I found myself frustrated, thinking I may have run into a glitch. Also, I soft-locked myself by getting my car stuck on a rock, lol.
This is incredible; I would love to see more stuff like this; if you made a larger version of this concept or something similar and published it on Steam, I'd happily purchase it. keep doing what you're doing :)
