The biggest problem i'm seeing with these games are the complete miss of the jam theme..
"Every week, the community (that’s you!) votes on the theme for the jam out of 5 themes we arbitrarily choose. We sometimes take theme suggestions too! Join our Discord (see below) to take part in that. ___You are free to interpret every theme in any way.___"
I'd say most games do fit the theme in an interpretation. My first time doing any kind of Jam and i had fun. Isn't that all that counts?
