Well, not bad, not that good either.
But looks to be your first flash game.
Graphics are a little rough, but the ability to have all the creeps show up at once is a nice touch, just a little overwhelming the first time :)
Poor Burnacid, you need to go and only play flash games in the shooting game section. Maybe killing will relive some of that pent up anger you have.
Oh game was good, simple to the point. Come on guys, how many games here do exactly what is said in the game description? Sure, no fancy flashing colors, but the physics are good, the shadows are right on. 4/5
