very interesting

i learned something today.

nice tutorial

but it's not very intuitive, dor beginners, this is boring, you could put some background music XD, but the content it's ok

helpful in the wrong place

It's a really nice and helpful turorial you made, but I don't think you should post it as a Newgrounds game, simply for it is nog game. Even though it's about making games I still think you should post it somewhere else.

Good job!

It may be just one method, but it's deeply covered. A need for this is arguable, but I won't mind. These skills and tricks are very basic, but will last a developer a life-time in debugging and testing. I think it's a fine tutorial indeed. Well done.

Useful

This tutorial would be very useful for begginers and it was very well explained if someone didn't know how to use the trace(); function, i do. However while i was reading i became a little bit bored, maybe add in some music, if you don't want to increase the filesize by adding music from ng, pm me and i'll tell you how you can add music from newgrounds without it taking up additional memory in your game.
