"Wings of Vi (Vi as in "Vee") is a 2D platformer created by Grynsoft, a small indie developer team led by Jesper "Solgryn" Erlandsen. Created in Clickteam Fusion 2.5, the game focuses on saving the world from a demon lord named Jeh'Oul. The game, a spiritual successor to I Wanna Be The Boshy, started development in Clickteam's Multimedia Fusion 2, but switched to Clickteam Fusion 2.5 after three months of development. Development started on July 2012, and the game was released on November 28, 2014. The game can be bought on Steam or the Humble Store."
