How thanks to report the bug. I think it's a matter of a button not correctly map. I will check to update this weekend the app. Maybe the good button is hidden on the left on the same height that "Start Game", If you click on it you can start the game.

I couldnt get passed the controls screen. :( I included it in my compilation video series of all of the games from the GameMaker Studio 2 Beta Jam, if you'd like to take a look :)
