I am trying to upload my game to Facebook. However, the game does not appear. Why is this and how can I fix it?
You can't upload a game on Facebook. You need to host the game on your own server with SSL capabilities, and then Facebook will show the game from your server to the players.
You seem to be using Construct 2. There is a great tutorial for publishing a Construct 2 game on Facebook. Just follow the tutorial and you should be all set.
