Note from Designer
The third iteration of a design called Tangereen (see the first two at https://www.fontspace.com/font/34404-tangereen ). It also has some influence from another design, Paradoxy Effect (https://www.fontspace.com/pixel-kitchen/paradoxy-effect ).
This one is meant for display and logo uses since it is much fancier than its predecessors. It still supports quite a few languages, though!
