Thanks for the feedback.
1. Yes there is a full-screen option on the game page it now gives details to zoom in by pressing O forgot to include that.
2. The icons on the top allow you to disable the background and the sound since it could be annoying to some people
Also, the reason why I'm not updating this game anymore is because there is another screen worth of content and the option to unlock will appear if you play enough. I probably should have made that more clear on the game page.
