Yup, and their reddit account that posted about the jam was deleted, there was no specified sponsor despite claims of there being one, the whole thing was organized poorly, there was no external communication channel like discord, their itch account doesn't have any other interactions other than for this jam, etc.
I was honestly skeptical from the start, but the potential prize money was too tempting for me to pass up.
But I guess I at least finally got to semi finish a project for once (even if late), gained some experience, and didn't waste much time since I spent only 3 of the 30 days on this jam.
