OpenGL GLSL - Text rendering query

[SilverWarior]

No, I'm not having a go at a competition... I did look at it, but if I recall correctly, you have to release sources... I'd like to make money from this endeavour, so it's closed source all the way for me right now

That is understandable. The same reason is dissuading me from entering the mentioned competition.

And yes, it is due to have a retro look... mainly text based UI for the entire game.

Care to share more info on your game idea?
