You're motivated! It's a good practice to add the documentation but my code is divided into more than 200 files and none are documented (not the time during the jam) xD It will be such a pain to do it now.. But I think that the majority of the code is clear/clean enough to be read and understood.
Fair enough. Most of my code is so readable, which probably was the only reason I finished. Probably the bigger systems are what need the most documentation, and some renaming of methods. Sometimes I would write a random name, and then all of the sudden be looking for it only to say "Now, why did I name it that? That's not even what it does!"
