I agree that WASD and a track pad suck, I originally had keyboard and an external mouse in mind when setting up the controls. I do intend on adding key bindings sometime in the future, it just got left behind for this version. There is Xbox Controller support, though I think it's lacking when it comes to interacting with shops, apologies. As for fullscreen I'm not 100% sure. There is a built in option through Itch, which is the arrows in the bottom right, alternatively 'O' is also supposed to toggle fullscreen. Hope this helps. Cheers!
