Thats a good question @Tako98, scirra will send you an email when your game is uploaded. Also, make sure that you went to the Scirra Arcade
and clicked the "Upload a Game" button. If you have already done this, then just wait for the email. In the meantime, click here
to play some of other people's creations (including mine) . Also, this is where you would find your game
once it's been posted. Enjoy Scirra Arcade!
