Are there Ballance levels beyond Level 13? Is yes, where are they available? Recently I saw on YouTube somebody trying to hoodwink people by showing Level 1 as Level 14.
No, there aren't. Ballance is a game developed by Cyparade where you can play 12 different levels. The level 13 was released for free on the developer's homepage. I suggest you contact Cyparade for further information. You can get in touch with them using the contact information from the official web page.
