Wow, what an iconic piece of Newgrounds history! Too bad I have no idea how the hell I'm going to beat the final boss, though. Definitely will be back to play again!
Edit: Yeah I beat the boss. Turns out I was stupid and just had to shoot the eyes to stop the laser attack.
Edit 2: The chicks with dicks poster might have been foreshadowing the final boss (spoilers: You fight a giant Cassandra, and she has a dick. She’s a chick with a dick.)
