I've tried designing "games" on Twitter, but limitations of the format and low API limits constrained the design in lousy ways. Instagram has slightly more potential in this area, but neither is well-suited to it (I'm sure they don't consider this a valuable user scenario anyway.)

@letsplaysnake ... They missed the opportunity to call it "Twit Plays Snake".

Neat, doesn't render properly on android Twitter app https://imgur.com/WS2jBJJ
