Ulydev, thank you!
davisdude, thank you HEAPS for the pull requests, I am a fan of proper spelling and grammar, and you really saved the day with the Eyes one! I added a note on the main page about window sizing.
I'm not completely sure which common practices you're referring to, feel free to let me know exactly what you mean, but I imagine my response would be similar to why OOP isn't used in these tutorials, or multiple .lua files aren't used, or the code isn't broken down into small functions, or isn't very "functional".
The short answer is: Because I don't think it would help toward the goal of these tutorials, which is to take people from the stage of not knowing how to think about programming a simple game, to being able to. For this, I think it is easier to think in terms of what "data" (as in variables/tables) needs to be stored and how it changes over time, rather than "objects", and it's easier if the program's flow of control is easy to follow.
There is probably a lot that could be said about all this, and the way I've chosen to do things may be surprising to some (or most!) people, so if anyone wants to discuss this kind of thing, please send me a PM.
josefnpat, thank you, I hope it helps new lovers!
paulclinger, thank you for your comments and for ZeroBrane Studio! I have added a link to the repository on the main page.
I know what you mean about it maybe being suitable for people unfamiliar with LOVE... I'm not sure what to do about it though. I could link to the pages about running games and callbacks, but there are other important LOVE concepts... and even then, what about people who are unfamiliar with Lua? I'll keep this in mind, I might even write something myself.
That JavaScript code is really nifty! It is true that the pages are quite long, but I'm not sure if having a table of contents would be that useful though, because unlike the ZeroBrane Studio documentation for example, the tutorials are very sequential and I'm not sure why someone would want to jump to a specific point. Let me know if I'm missing something.
easy82, thank you!
Zireael, sounds good to me, somebody should make one!

If anyone wants more simple game ideas for tutorials, let me know, I have a few.
