I Wanna Flip The Sky is a homebrew NES platformer game, along the lines of I Wanna Be the Guy and Battle Kid, developed by Tom Livak in August 2012 for the NEO Flash contest. There are 12 one-screen levels where players must avoid spikes, walk on conveyor belts, and walljump on specifically marked walls to make it to the exit door; players are given the ability to flip a number of times in each level.
Asumeh completes the twelve levels present in this game in record time.
