In, but just the tip.
Howdy, y’all. I’m in again unless I’m not. That may seem a wishy-washy attitude, but it’s gotten me through 4 LDs so far.
Language: Javascript and the lovely HTML5 Canvas element.
IDE: I tend to alternate between Aptana Studio and Geany.
Art: Paint.NET all the way, baby. Also might try out pickle (It’s a sprite editor thing).
Sound: Audacity, BFXR, Walk Band (Which is a name that doesn’t allude to anything), and maybe a bit of my own voice.
Furthermore, I have some pre-written code to declare. Quite a lot of boilerplate type stuff in Javascript. I find it really useful, and if you want to use it you can find it here.
