I have somewhat of a soft spot for games that take place in environments typically visible only under a microscope. That's probably what drew me to watch the trailer for Cyto's Puzzle Adventure, which originated on iOS but is now up on Steam Greenlight.
Cyto is apparently some sort of microorganism who travels through cytoplasmic environments via a stretchy vesicle that allows for attaching, detaching, and slingshot-style launching. I'm not sure exactly what Cyto canonically identifies as, but it reminds me most of a rotavirus, which causes severe diarrhea. "Breathtaking emotions" indeed.
