Okay, my exams are over. My BTECs are signed off*, and i'm ready to start work again. I plan to have this thing out by the end of August. I'm mainly just trying not to go for a 3DRealms mentality of 'when its done', if i'm totally honest.
Meanwhile, for those with Portal 2, I entered into the Portal 2 Mapping Contest over at ThinkingWithPortals. The final map, SP_CORECIV, is riddled with bugs, thanks to a deadline of about a week. But hey, it works, if you read the buglist. I'll release a bugfixed version this week, but it probably won't be entered into the contest. Seems a shame to waste 90 hours of toiling. Oh well.

*They aren't actually signed off, but its probably gonna be a matter of days before they are.
