A 10% royalty payment is buried in the license. There is no mention of this on the website or github page.
Hostile royalty stipulation in the license, stay away
The name and the hidden royalty both sound pretty horrible. Very Good Scam, rather.
My first impression was that NOGAA would be a better acronym, this stands for NO Graphics At All given that I was greeted by a blank screen with some dancing dots. After feeding it the required permissions the screen remained blank while the dots danced for a surprisingly long time after which I was greeted by an underwhelming page with a textual header which did not fit inside the display nor could be made to do so. The rest of the page looked like your bog-standard landing page, nothing next-gen or advanced about it. Did I miss something or is this just not very interesting?
