I didn't know about this until like ten minutes ago (thanks Wyatt) but now I gotta do this. This'll be the sixth LD I've participated in, and hopefully the third one where I actually complete a game :)

I want to use Godot 3 for this--I don't have a ton of experience with it, but in the realms of all-inclusive game IDEs I find it much more immediately approachable than say Unity--and honestly, it's time for me to learn one of these big hulking things. Art will be Photoshop, music (if it all??) will probably be Famitracker.

Here's the game I made for LD40: https://ldjam.com/events/ludum-dare/40/junk
