Basically, you have to discover the platforms hidden in the environnement with your orb and the butterflies. Shoot a butterfly on an invisble object to make it visible. Try to reach the one witht the blue particles shining in the air.

Wasnt quite sure how to win, but the graphics are really nice. I included it in part 1 of my 7DFPS 2014 compilation video series, if you would like to take a look :) http://youtu.be/Rsqo3mkxC4s
