You clearly put alot into this game...
and it certainly shows. I LOVED the whole idea, taking newgrounds icons from all-over for one final battle, and overall it made for an awesome effect. The gameplay itself was excellent: enough variety in attacks to keep it from getting repetitive, and no annoying glitches or problems to speak of. The character choices were perfect, taking a few characters that clearly needed to be in there (pico, alien homnid, tankman) and a few that weren't so obvious, but clearly deserved to be on there as well (piconjo, p-bot, convict). The differences in the characters abilities suited them well (i.e. salad finders was slow, as you you would expect him to be in the movies). There's so many more good things to be said, and so few bad things (basically none), so I'll just leave it at that. Five stars easy, and even though I've beaten it: I still keep playing, which can't be said for most games on newgrounds.
Oh and btw, p-bot is the man. Loved how you could find a character that has never been in an animation on newgrounds, but is still a true newgrounds icon: I'd bet off the tops of their heads, very few people would have come up with him to be in the game. And now he's by far my favorite character.
