After seeing Zax's dungeon idea randomizer and helping him work out some bugs, I ended up on a bit of an HTML/JavaScript kick. As a result, I made my own randomizer, this one for Zelda Classic enemy pools. Ever find yourself using the same few enemies in your dungeon a little too often? Want to put your players at the mercy of the odds? No? Well screw you, buddy, this thing took some actual effort to make.
To use it, download the file off of dropbox and run it in your web browser of choice. Select your dungeon's enemies from the pool, set your enemy density, and start generating.
IDK if this is something anybody else would find helpful, but I figured I'd share it anyways.
