The developer appears to be QG Studios for the Roblox game Yeet a Plane Simulator!

Quick note

I couldn’t verify a game specifically titled “Yeet Simulator 2019” , so this may be a different Yeet-named Roblox game. The closest match I found is Yeet a Plane Simulator! , which is listed as created by QG Studios.

What I found

  • Yeet a Plane Simulator! — creator: QG Studios.
  • Another Yeet-themed Roblox game, Yeet Cow Simulator , is attributed to Rollipop.
