This LOC chart is recorded from random points of the last year. It shows some kind of progress in lines of code, but is not equivalent to real progress (which is slower). The problem areas in the source code are now kind of distilled to a number of difficult puzzles I have to solve one at a time. It's slow, slower than any regular game development. If there is one thing I'm happy about it's the extremely low number of bugs, thanks to my ridiculously strict and ultraprofessional programming style. Unlike many developers I don't have to waste my time fixing bugs, but I do have more problems with algorithms and larger program flows than any regular math-aware programmer. In the next exciting blog text I'm hopefully going to tell good news about level themes.
