Thank you for playing! Yes, the x closes the game. It was supposed to close the game on the windows version and take you back to the menu on the we version. It was also supposed to ask you if you really wanted to quit. Sadly I ran out of time and it just closes the windows version and stops the web version :( Im really sorry you couldnt see the end, the new update wont be so dependant on your coins. Thank you for your feedback!
