After realizing that I have never released a game myself, I decided to make a series of tutorials to help other people. It's not exactly the clearest tutorial to follow but I tried to make it as understandable as possible.
If you find that I didn't explain something well enough and you can't follow the tutorial, you can download the flash file here:

(without any spaces)
Feel free to tell me if you want something added to the next tutorial or if you want a tutorial made. I'll try and find time to make new ones.
