Guess I meant this game uses GLSL and OpenGL 3/4 whereas my previous projects were OpenGL 1/2 with fixed function pipelines.
Seems nice but did you just list "Shaders" as a graphical feature? How else would you render a game these days ?
Most of your OpenGL tutorials and thus a disproportionate amount of indie-games using OpenGL use OpenGL 1/2 still.
Added some screenshots to the OP.
