If we said WOW at the end of the last chapter, we'll give a HOLY COW to this one. All of the playable levels of our game are now complete. Take a break. Let it all sink in. This was an enormous deluge of information. Believe it or not, we've only just begun! In the next chapter, we'll cover some advanced features to polish our playable levels, create our next two rovers, complete our UIs and menus, and get on the road to making money with a monetization structure!

Brace yourself, take a deep breath, and let's do this!
