My speculation is that it's gonna involve something 'Hand Crafted' :P
Okay but actually, it's gonna be interesting to find out what creative takes the theme will allow. Would be awesome to see a ton of games that use assets made outside the digital realm, for instance!
Part of me wishes for the theme not to be something meta, that reminds us of why we even need a jam like this in the first place. But maybe it can also be cathartic to have a theme like that. Looking forward to the reveal
