Idk how it works but I took screen shot and I am making game based on it.
Yep, that's it -- just run RNDGAME, get it to generate a name you like, then make that game!
You can post that screenshot to Twitter with #rndgame2021 hashtag if you want. Some folks are sharing their fun names. (Can also share them the name thread in Community posts for the jam.
That is... assuming you got here through the RNDGAME JAM!
