Started the game jam with a fresh install of Linux Mint. Nothing is like a real challenge!!
Going to use Gimp, Aseprite, Audacity, Vim and FreePascal as the toolchain, all open source projects. For now I will not submit for other OS;es then linux, but source code will be published on github - "Write once, compile everywhere". If I have time to spare (I doubt it) I will try to compile and submit a Windows application.
God speed everyone!
