I just put the updated "almost ready for prime time" Bulldozer editor up here. This one allows you to design a level and record a solution once you've designed a level.

To-do list consists of finishing the leveltotext() and texttolevel() functions so that it can actually read and write levels, both to the clipboard and to the server.

And, of course, the ability to actually submit a level to the server.

Only bug I know of right now is that the shift-n-rotate buttons don't clear the solution as they should. And the shift left-right buttons don't seem to be working.

Give it a try and lemme know what you think. Since it's a Flash app, I intend to just put instructions under the applet in HTML. If there's anything confusing at first, lemme know.
