I and madgnomegamer are going to enter the jam.

engine:
Stencyl 2.1 – I did use another engine recently, but I am familiar with Stencyl
I created a quick test game and uploaded it to Kongregate

music:
Autotracker (modified by me) and Audacity

sounds:
as3sfxr and Audacity

art:
Photoshop or pen&paper

I may use some of my random content generators, too.
It will be a problem that madgnomegamer and I have ~12 hours time difference, but we will handle it.
Good luck and a fun time to all contestants!
