jb_stormfront
Takes place during a rainstorm has some pretty epic minigames and is the best jb map ever. I swear I am in no way biased.
jb_bricks
Mix of mlcastle and supermario with brick textures nothing really outstanding but I guess its worth a shot
Final has all the fixes that our current one has but it shares way more in common with the original casuarina which it seems some people (including myself) prefer.
