"Scetches"
To make this engine, we have used big amounts of paper to try to get our head around problems, and to explain theories. Here are most of them gathered.
"Misc testing"
It is not always the best aproach to test new algorithms and the like in the game engine it self. So many times we have buildt small testing apps to test different drawing techniques. Here are most of the screenshots from the various testing applications.
"Map Editor"
Wossname have made on of the sexiest map editors ever for this simple game. And it needs it's own section with pictures. Have a look your self, and remember there is a beta all ready possible to download on the download pages.
"In game screenshots"
Even if it says in game screenshots, there might be a few pictures here from the map viewer NoteMe made. It was a small not very supported app he threw togheter so those who made maps could see what it would look like when playing the level. Except from that, the rest of the pictures are from the engine from early stages untill the end.
