Fine, have some maps.
I’ve made a couple of post-compo modifications to my entry.
The main one you might be interested to hear about is that solo play is now possible. You can load and save by double-clicking the relevant buttons at the bottom of the editor. I just whipped up nine demo maps, included.
Note that you can’t overwrite a map, so don’t worry about that. Every time you hit save the map gets a unique filename which you can mess with later.

Besides the time considerations I originally didn’t want to include saving at all, because I thought that feature might deemphasise the interaction between players. But since I haven’t gotten much feedback from people who actually have another person to play with I thought I’d open it up a bit.
