I'm missing style files (although all the levels probably use the same one, I'm guessing) for the following levels in Insane Steve's pack for cheapo:
Menacing 21: the Ob3lisk
Chaotic 3: Round Trip
Hopeless 19: The Mon0lith
Also, I found a version of the Shadow style, but the Shadow levels in his pack don't work anyway! Maybe the style pack should be renamed to something different?
