If you want to delete a game, click the cog icon in the Project menu and click "Un-Publish Project". This will remove the game from being accessed publicly.

Excuse me, but the game does not function.

I click play and it does not begin the game.

got to menu screen for nothing to work. tutorial didnt work, the website link brings you to a dead page, and the play game flashes to the same screen. rip at least it loaded
