...and not long after publishing that post, the washing machine decided to blow up, shorting out the fuseboard and killing my computer. Had I saved my progress in Space Crusade? No I hadn't (in my defence, the save mechanic is kind of fiddly). Ugh. Can I be bothered to go back and replay all those levels? I'm not sure. Needless to say, it's going to take a while longer than I originally planned to finish it now. Bah!
