Of Two Minds
A downloadable game for Windows, Mac OS X, and Linux
Created by Michael McCollum (@gnustoboz) as an entry into the May 2014 Public Domain Jam.
Inspired by and including the poems "Invictus" by William Ernest Henley and "Alone" by Edgar Allan Poe.
An in-game controls reference is included, but in short, hold the left mouse button to fly forward, and the right to fly backward. Holding the space bar will increase your flight speed. Use WASD (or the mouse, while holding a mouse button down) to change your direction, and Q and Z will hover up and down, respectively.
