Just like to say I'm loving programming in Cobra right now!
I started writing a chess program in Pure2d, but I really wanted to write an arcade game. An arcade game has some unique problems and it's very easy to write a program that is a nightmare to de-bug and is difficult to update.
With this in mind I decided to write a simple arcade game using Cobra2d in a modular way, and also a tutorial to go with it so others could use it as a framework for their own games.
I'll release the example game first for testing. The tutorials will then follow - in stages rather than altogether.
