Not stupid questions at all. If you click the banner/link below or above it will take you to the product page for the game series. You can install this game on any computers you own. Our only real request is to please not give it to friends but to support Dave and Panther Games. We made the game so it can simply be installed on all the computers you own or use. Our store will keep a history of all the products you purchase from us and allow you to re-download any of them when you want.
I can't speak for Dave on the Linux port but I would expect that to be a no.
