Destroyer
Pirate Apprentice
I managed to use the controller map I used from my post about controllers from pirates online along with steam link on mobile to get the get game functioning on a phone. Now, I could have made it fully wireless with a bluetooth controller, but I do not own one of those, so I was tethered to my computer. If you are able to do this with a bluetooth controller, you could technically go mobile (as long as you are connected with your wireless network)
