Awesome game

Its as awesome on mobile as it was on PC. The problem I have with it is that I cant use the profile I had on the Steam version and put it on here, because I cant remember what the name was. its been months maybe almost a year since they dropped it from steam. Is there any way to find out what my username for it on PC/steam was so I can use on mobile, or do I have to start completely new?
