Hi, there! I've been working on a mod for Aquaria; mostly ideas so far, but I have a rough world map and a good chunk of the story done. I won't go into detail with the story since exposing it bit by bit was one of the things I enjoyed so much about Aquaria, but here's a shrunken screenshot of what I have so far, story-wise, to lend some credibility to the mod. The first page (plus a line) contains the story and major gameplay elements, which cover about a third of the world map below. The rest is notes on the same and more.

For better or worse, the mod is fairly large in scope (probably smaller than Sacrifice and Lost Treasures, though) and is tied to the main plot of Aquaria. I also intend to mimic some of Aquaria's narrative style a bit, elaborate on the lives of some of its more mundane inhabitants, and perhaps let a bit of good-humoured parody sneak in somewhere. Combined with the fact that the protagonist is a pierogi, prepare for a bit of silliness. At first, the idea of following the life of a particular pierogi in Aquaria was just one to amuse myself, but I eventually decided I could make it work. To get ideas for filling out the story a bit, I read up on Polish legends, and now I've based some of the bosses and bits of the story on them. They're pretty cool legends, so I think they'll make the mod more interesting. And anyone out there who's familiar with them already will hopefully get a kick out of seeing them.
Here's the rough world map I mentioned above, as well as a sketch I did to get me started on the beginning area. After I worked on the story a bit, I decided to use the sketch for the title screen instead, and it even plays on Aquaria's title screen a little. :)
