Been working on this one for a few days. It's a Metroidvania mapper!
Going to post it when I figure out how to use Custom Blocks to make it a little easier to use without needing complicated math to get information from the map. It's also extension free and 100% vanilla stencyl. Anyone can use it, even the version 2 guys.
It's almost completely dynamic aside from having to place a few actors to define the map tiles, but that makes it incredibly cusomizeable. It features multiple worlds, special points of interest like save points, can draw in known but not visited parts in grey, and is light-weight on performance on any platform.
