WOW flawless
It is extremely rare that give a perfect 10 to game but this one deserves. Perfect gameplay, a very very diverse amount of enemies, and awesome weapons all useful in their own right. For those of you have trouble with specific levels and calling the game to hard, it is you who screwed up. If you are not careful with your money then you will buy the wrong weapons making some levels seem impossible(that would probably be the only flaw). If you want to see what a few weapons do, play a few times and just buy weapons to try them out. Also, hold out as long as you can without buying any weapons. Many weapons you buy early will only be useful shortely and you may have made levels easier when you just needed a bit more practice. I disagree with the list of top guns in the game. You listed some pretty weak weapons in some cases while leaving out some important ones. The Lightning weapon is one of best and may be called essential in some levels and also makes some difficult level very easy. Some people have been saying the duck weapon is useless but I found it very useful. It can cause a lot of damage on one big enemy or take 30 small enemies. I hope to see more awesome games from you. People will have high hopes because of the awesomeness of this game which is clearly one of the most solid games to hit newgrounds yet.
