Interesting game play, but there are a few problems. First, but this problem has appeared for me the last few weeks with Newgrounds, is that i can't see the whole game in newgrounds window. But like i said, probably a problem on newgrounds.
The game itself is fine, but like another person here said, the graphics need an improvement. Some story would be nice too, since you went out of your way to create a ninja and "aliens", even if it is a silly story with comedy, at least something.
I even read the how to play thing.. i still don't understand and still die.. but its a pretty well thought out game.. but the ZAP doesn't do anything and the Teleporting should be more then one freaking square.. JUST so you know..
TRY AGAIN.. you'd make good games if you thought it out a bit more.
btw, ZAP kills aliens around the player ^^
It took a while to figure out, but the gameplay itself was pretty fun and challenging. Had to knock off a couple of points for the style (especially, the Comic Sans). With a facelift, this could be a marketable game.
Got it! Thanks for the comments.
