Tay Zonday's Dome 2

Behold, a screenshot from Super Scumbag World! I wanted to make a level where you have to protect something from attackers, but the darn block wouldn't work. So instead, you have to hold onto a shell for dear life and not let anything crash into it.

It's not as difficult as other levels I've made, because this one uses open spaces rather than tight little corridors like most of my previous stages used. And because the water is frigidly cold, you die when you try to swim in it, yet all the little fishies you encounter can swim just fine.
