I shall participate!
I'm not feeling the most motivated and I've got a lot of things I need to get, but LD has always important to me so I will make something.
Here is the software and base code I plan on using:
Programming: Visual Studio 2015, C#, Monogame, Notepad++.
Graphics: Paint.net, Autodesk Sketchbook Pro
Sound: Famitracker, Audacity, and an Ukulele.
Base Code: My custom engine, (the link also has a sample game to see it in context).
