Upload here, of course. There is a section that says "JAR class name — Enter entry point of game, eg. io.itch.MyGame
My code is pretty simple and I use eclipse.
When it asks for class name, I'm not sure what it wants me to write. TicTacToe2() ? public TicTacToe2() ? new TicTacToe2() ? io.Itch.TicTacToe2 ? Either way, I tried a couple and none of them worked...
