So far this year I've completed
"Peril" - my TINS05 entry,
"Sidescroller" - an entry for a small 48 hour competition
"Jack" - an entry in LD48 #7 - in the showcase
and I'm working on my final game of the year, my Allegro Xmashack entry, which is looking pretty nice.
The theme? Well, they all use hardware opengl and aren't (quite) 3d games. I'm getting to the point where I can actually achieve useful stuff quickly with opengl. It's good.
