Work on it.
Hans did a decent job on his voices, but I don't think he was the best choice for the Joker. Arin was a great choice for a satirical batman though. If you plan to redo this, then try using Joshua Tomar (TomaMoto on NG) to do the Joker. I also like the reference to Yotam Perel's "Nameless" Series. Just epic, but it's obvious you traced the pictures from Nameless 6 Vol. 2.

Moobilly!
I like the upbeat tune to this flash. I also like its "kid's imagination" type of feeling to it. You feel as if you're dreaming and the world is full of unicorns and unis and corns; all that good stuff.
Food for thought.
Here's a suggestion: Flash tools + Sprite images= chance of being zero bombed. It depends, actually, on how you use it. You, my friend, did not use it the right way. The gradient gives it all away and the sprites lose its feel. Also, work on touching up those Mario and Luigi sprites; they're all blurry. Also, if you plan to use a super Mario sprite, use a super Luigi sprite to go with it. A large Mario and a baby Luigi offsets everything. The duo were meant to be a duo, not an unbalance in the scales.
Y'know I'm not actually gonna use sprites except for the parts were u play, and some animation. But mostly i'll be using my own drawing. Well not my own, I hired an artist to do it all for me. This is just a trailer to show the box art, and see what people will say about the idea, i'll be doing another trailer soon.
Good.
Good first flash (I know you hate the phrase). I will vote to see what's fit for this flash by examining your overall ability. I say, for a first flash submitted onto Newgrounds, this is good! You probably trained to make a substantial flash before you did anything, right?
Oh, and where the hell did you get those Shoop da Woop sounds?
Tssss....
Man, that chick was hot! Too bad the protagonist didn't sign up...probably was never trained for mano-a-mano (hand-to-hand).
You wah fortune cookeh??
Good script and okay art. The lip-synching is totally off, though.
No shit sherlock. I posted it in the description
Buggalicious!
There was a little bit of a bug in your animation...probably just a bug in your ActionScript.
Right after, rocketship and the missile hit the meteor, the audio just stopped there...weird...
If you used a song in your flash and you can't remember it, just look at the mp3 properties (if you have Windows).
Yum.
Very good collab, actually. Lengthy parts, though. I like Dim's reference to Metroid Prime, spoof or not.
Okay.
Not the best flash you've made, but good, nonetheless.
Some of the parts were kinda unrealistic, though. Why was Tom's hair bleeding, for example?
Turtelss...
Is it just me, or is Blockhead truly a blockhead? What does he have, ADHD? Down?
