This is kinda... old.
5/5 and 9/10 for the anti-spammer message, but by the time I played this, the Star Syndicate was no longer the premier spam group on NG. The Kitty Krew is. You should make something similar, where Wade Fulp and/or Tom Fulp goes through the lairs of certain KK front groups and allies (right now I'm seeing the Owl Organization in the Portal, that was formed under the supervision of BigFuzzyKitten), fighting their bosses (in the case of OO, that would be BigOldOwl), and eventually reaching KK headquarters, and at the very end, fighting BigFuzzyKitten. Yeah, I'd play that one. Ooh, and maybe you could find a way to make it more like the original Metroid, with exploration and fast moving action in balance, rather than just action with no exploration. That would be the best game on NG, even outdoing Newgrounds Rumble, if done right.
