Supermuzhik - Superman vs Darth-swiner and Bat-pigs armada
You play as Superman and you're supposed to grab humans (with the mouse click) and throw them at the enemies! So basically humans are weapons in this game. What an amazing and original concept! The enemy is a flying pig-thing with some sort of rotating blades or something (maybe hands!) and it's coming right at you following you wherever you go. You collect yellow coins for bonuses and power-ups (which disappear after a while) and all kinds of weapons. One of the coolest weapons you can use is a chainsaw. When you finish up the level 1 you can go to the settings screen to find all kinds of powerups such as: an extra health, flying speed booster, coin magnet radius, special combo attacks, push defence shield, teleport activity and a lot more.

When the music changes that's the sign that you are entering the boss battle and a guy you will be fighting with looks like a flying Shrek-pig or Darth-Swiner. But don't understimate this guy just by the way he looks, it's gonna be tough. He flies all around the place and he's not easy to hit. And it's not gonna be easy to pick up the power ups having him on your backs.
The game is long for a flash game and it will probably take you to beat it about an hour or so. I didn't expect flash game to have that much replayability (famous non-existing word so commonly used when refering to playing video games).
