Somehow I managed to squeeze a bit of development into this evening (thanks Maria for letting me work) and I came up with a simple menu. At the moment only the Play and Quit options work, the other items are placeholders until I can get a bit more time. I worked until 7pm this evening, so coming home to a cooked dinner then being able to spend an hour working on Fasteroids is a blessing.
I managed to test the Linux binary on a Xubuntu 16.04 system this afternoon. There was no issues other than the typical issue I have occasionally with USB headsets (1/8 inch plug headset worked).
