So, the version that I made doesn't include:

• Tuber Customization
  
• Trending Topics
  
• Room customization
  
• Rooms
  
• Puggle
  
• Basically anything
  

But it does include:

• Creating videos
  
• Views
  
• Subscribers
  
• Upgrades (when you get more subscribers)
  
• Player level
  
• Cloud leaderboards (with usernames!)
  

Check it out if you want to!

Note: I'm currently working on the username part of the leaderboards, so it might not work as intended.
