Update time...
I wish I was here to tell you that A: SD is ready for beta, but I'm not. There are two reasons... I thought I was going to be able to work on it pretty much full-time over the last month but, you know, life happens and stuff. I've gotten an awful lot done, just not as much as I'd hoped.
The second reason is also good news. I've completely overhauled a lot of systems, like the NPC/enemy AI (which is entirely script driven), and added some new features. A: SD is very script heavy so this overhaul made a big improvement in terms of performance. It needed done. It's also allowed me to do a lot more with enemy based puzzles as well as cutscenes and storytelling, adding a bit more depth to the grunts' world. There will be a few surprises that I hope you'll like.
I'm not going to make the mistake of giving you a date until I'm more sure of it. It'll be ready when it's ready, but hopefully that won't be too long. I will, as always, keep you all posted.
Just keep up the good work! You know what they say - a good work getting done takes time ;)
