This is so much fun. The way the worms warp by 90 degrees, but their controls don't also go under the same transformation, is a perfect balance between making things confusing and various but keeping it manageable. Whenever things get messed up, at least you can manage to make them all go the same direction again in a couple turns.
The presentation is shockingly cohesive for 48 hours. Especially sonically. The way the worms move to the music, and the way the sound effects sit so nicely into the chord progression, and the way that adding on another screen does the same, plus the transition between being above/below the earth.. I don't think I have anything to complain about here.
