These have probably been discovered before but anyway 1. There are no shields in EHZ on S2B 2. The fish badniks jump up at different speeds 3. The spikes don't appear at this area in S2B 4. You can jump in between the waterfalls on S2B unlike S2. 5. Shields again. 6. This area is closed in S2B. Screenshots: S2B on the left, S2 on the right. I will try and find more differences later.
