You're right that's my bad. It was Player First Games that was acquired. This is a bit sus, especially considering there's been no reply. This is my first game jam, is it common for the people running them to try to steal others work??
I don't know what's common or not but considering anyone can make a jam, you just need to be on the look out for anything fishy, even in big jams people make alt accounts and all sorts. Honestly this one is clearly just some random person who want to try publish a game, they can't even make a decent logo. I would avoid this and do one of the actual good looking jams with cash prizes etc
