After getting tired of people repeatedly telling me I'd misspelled 'desert' I bowed to public pressure and renamed the game. I dunno, maybe my sense of humour is just too dry for most people! :-) 

 I also plan to:

1. Make the difficulty more progressive  

2. Make it clearer what I mean by 'strafing' as I've noticed a few people don't understand this and end up dying.... a lot.

3. Add a fullscreen option, which means investigating scaling.
