Good but, get the free PC download first.

This game is ADDICTIVE. The first few levels are easy then suddenly the hard stuff gets thrown at you. If you know what I mean, it's the frustrating king of hard...you know. Almost, almost, and you die, making you want to try harder but after a while it gets annoying. Another little thing that annoyed me is, robots vs. ninjas, I mean ninjas have weapons (yes there are no weapons) and don't fight robots (with sucky AI and yet it's still hard...). Also what's with the 2nd screen. I know it's a DS but the other screen could have been used for something else (I can't think of any thing right now but, something). The level editor's fun to play with but that's the only thing that sticks (at least it sticks). Also about the PC download (it can also be played as a flash game online but, it's free either way). The website's at the bottom if you want it. It has different levels but the basic concept is the same (Note: There's no level editor :-( ).

In the end, get it if:
1.You liked it on PC and want it on the go
2.You like to be frustrated by games
3.You're poor (it's only like $20)
