I know this topic has been brought up before, but I find it an interesting one. What would you rate the levels that come with JJ2?

For me, it would be:
Battle1 - 8.2 (Good design and layout.)
Battle2 - 7.2 (Too small, springs annoy me, some odd ammo placement.)
Battle3 - 7.0 (Not that good, horrible ammo placement.)

Capture1 - 6.7 (Shield, bad layout.)
Capture2 - 7.2 (Okay layout.)
Capture3 - 8.0 (Good layout, weird flow.)
Capture4 - 7.5 (Good layout, odd flow.)

Treasure1 - 7.5 (Okay layout, good gem placement)
Treasure2 - 7.2 (Odd but good gem placement)
Treasure3 - 7.5 (Good gem placement)
