This page will contain subsections with different tutorials on how to do different thing with the Reggie! editor.
Screenshot have been taken from my first level (found here), which I made for this guide :)
► Page 1 - Areas, Zones & Backgrounds: What are they, and how do you use them?
► Page 2 - Tiles, Sprites & Layers: The simplest of the simplest, or not really?
► Page 3 - Entrances: Creating different kinds of entrances (normal, pipes) and configuring them.
► Page 4 - Level Start, MidPoint & Finish: You find them in every level, so you'd better know how to use them.
> Page 5 - Other Stuff you might need (Star coins, Water, ...)
I'm open to suggestions to add more, but remember, I'm not an expert :P
