Thank you again for the feedback FrowningAsinus. I don't think I will be composing anything for this particular jam. I am capable of it but am very slow and only know tools for the NES platform. Maybe for My First Game Jam Winter 2017 my first will be learning FM composition software :)
I've seen the Godot Engine mentioned time and again. I finally googled it and am very impressed. I am a fan and supporter of Open Source Software and it seems way less technically restricted than GMS 2 in terms of the scripting language. I did not have any firm goal for the weekdays set. Now I think I will try to convert my existing project over to Godot Engine. If I can get that done by Thursday night I will not have lost any time on my jam plan. If I do not get that done then we'll see.
