Final Update
Game has been submitted. Remaining true to my brand, it seems like roughly 80% of the work got done in the last 48 hours. Every time I thought I was done I'd test it and something else would have somehow broken - I really wasn't intendind to leave it so close to the deadline. I think I managed to catch everything (this time) so its now open to all. Placeholders have been replaced, a limited save system installed, and an 'endgame' is in place.
This has been fun, but I think I really need to brush up on my basics - maybe then I can be not quite so confused the entire time. I can definitely say it was a learning experience.
I'm gonna go sleep for 12 hours then I'll be back to try out some of the games people have submitted. I've been having a look (in between periods of shouting at code) and they look really interesting.
