That was one of the crappyest Pokemon killing game I have seen work on This game.

It would have been good, but a few points killed it:

The images were badly cut (you could still see the white outline).
Too few pokemon to kill
The end level is just sick.

If you hate pokemon so much, why did you go to the trouble of making a game about them?

One more thing, is the last level meant to be possible?

Judging from the description of this game that you gave in the author's comments space, you seem to have some serious anger management issues regarding Pokemon (although considering the atrocity of the drooling child media wave it's been turned into over the years, I can almost sympathize). It seems you took the Pokemon from still-frame shots from a player's guide or similarly styled article or website. I like how the sound effects for the gun shots came from Star Wars. Do I just suck at shooter games, or were those little blue guys firing ungodly fast for furious amounts of damage? Maybe slow them down a little in the first level. I thought the second level was all right for that although I can't say anything about the third!

Ok...The whole "Hey! Look at me! I made a Flash about killing pokemon cuz they're so gay!" thing is really old now...Although, the shooting system wasn't all that bad. But, there was no way to predict or dodge damage, so it's pointless. If you get an original idea and implement it in a better way, then you could make a fairly good game.

The targetting crosshairs didn't follow the mouse quickly or accurately enough.
