I forgot to put ßattlepack! and Night Cruise in the list, but that pack and that level were removed from J2O. Probably because there were no reviews(?) or the author wasn't satisfied or something. But P4ul has used Diamondus Beta 7 times, and worked on The Lost Battle Game's eye candy which makes it 8.

And Sacrush: I hope you can surprise us when your level is finished ;P.
