Not successful!
Unfortunately, I am not going to be able to complete this Jam – I spent most of yesterday setting up FlashDevelop, as it appears that I do indeed need to get away from the Flash CS3 environment.
As a result, I knew I wasn’t going to be able to make enough headway for myself to be satisfied, so I’m spending this weekend just learning the quirks that change (For example – it looks like I can’t use MovieClips to control animation.).
Good luck to everyone else!
