Sewer Escape 2
Uh, that stinks! Literally, because after you and your hamster friends escaped the lab you are trapped in the smelly canalization again, where your brains mutated caused by contaminated radioactive areas. And now you know, that you can get out that place. To play Sewer Escape 2 you just have to launch yourself. Keep on clicking with your mouse to fly higher and further as you collect golden coins and items for upgrades. Much fun.
