Thank you

Yes, the maps were created with an editor. (see this post) They are basically a 2d grid composed of numbers. I used notepad at first, but I quickly realized that it would be a pain to test the levels and then change something. This editor allowed me to sort of 'paint' the maps. It really works very quickly. The 'PGD' was sort of a joke, which I thought would be appreciated

I was wondering. I'm considering doing a post mortem. Would there be an interest for that?
