Brilliant
Aside from a few minor flaws, this game was brilliant. Pleanty of levels and characters for the gamer to choose from, as well as a wide selection of weapons (many of which seemed a little too powerful ;P). This has to be the best game of Newgrounds, and I'll be looking for the multiplayer expansion you mentioned to another reviewer. No pressure on you or anything, but I just think multyplayer would make this game flawless in every perspective, despite the few minor flaws I will now mention:
Some of the weapons seemed far too powerful, such as that strange blaster thingy on the Aztec level. Sure, it adds a bit of a challenge, but I think it gave me a little to much frustration. On the other hand, a player's frustration is a good sign for most any game.
I found the game a little too fast-paced for my style. I think you should go for bigger levels where it's easier to maneuver and strategize.
Well, that's about all I have to say. Oh yeah, and this is to all the noobs who say "dude this crap sux go kill urself": Why not try Flash yourself? See how quickly you can come up with an extremely successful frontpage award-winner, and THEN you might want to come back to this Flash and truely appreciate how great it is. Flash isn't easy.
To conclude my review, I'd just like to say that this game should be up on the frontpage for at least another month, and that this author's name will be known among us all one day.
Good day to you all.
