Dropple Worlds Progress - Part 1

So I'm a week deep into Dropple Worlds. I've been thinking of this project as 3 main pieces - the level editor, the main game engine, and content creation (building the levels, making the art and music, etc.). I'd estimate that I'm about 25-40% done with the level editor at this point. It's almost like building an entire second game within the main game, but the benefit is that it makes adding new levels much easier, which makes for a longer, more enjoyable playing experience. I'm planning on allowing players to create their own levels (similar to AutoTanks), so I think it's worth spending the time to make the editor full-featured and easy to use.
