Couple of other entertainers

Well here's a couple of other games that belong to the "wow" category-

Ricochet Kills 2
This one's a beauty. You control a stationary character at the bottom left end of the screen. The objective is to kill all the other stationary characters in the screen. You have a gun (with 8 bullets per level, i think) with which you have to shoot 'em. The challenge is to use as few bullets as possible. The bullet ricochets off objects in the screen (as the game's name states), so you get to plan your shots. Recommended to kill time big time!

Blosics 2
You get to control 4 types of balls, and the objective of the game is to make all the green blocks on the screen to fall off. Pretty interesting, keeps you occupied as the levels get tougher as you progress. Each level has a challenge to it, so it adds up to the interesting-ness of this game.
