I don't know what tool I'll be using. I might use my normal Flash tools I've used previously (http://ludumdare.com/compo/2017/04/21/announcing-code-base-for-ld38-flixel-project-template-publicly-available-for-ludum-dare-use/#hidepopup is the link, please let me know if you can't find something). Or, I might use Tabletop Simulator and a combination of other things and actually try a board game / card game for a change.

Or, I might go completely nuts and try to learn a new tool. Yes I know that's always an impressively bad idea. :P
