"Is Paul here?"
The premise of this game was hilarious, although it went on for too long (I played for half an hour and then finally started ramming asteroids). The hobo dialog was fantastic ("Is Paul here?"), although it started getting repetitious after ten minutes or so. Maybe you should up the asteroid damage so that an average player won't last longer than ten minutes or so, which would solve both problems.
Here's some dialog ideas, if you want them:
"I love this song."
"I used to work for NASA."
"Can you believe I built this thing out of a water heater?"
[While getting money]
"Cool, a state quarter!"
[After the rocket gets wrecked]
"Knew I should have double-wrapped the duct tape"
"I can see my former house from here."
The scuttlebutt is that the rocket is supposed to look like a penis, but honestly, I just don't see it. What's the point of making a rocket with two hobos attached to it look phallic? I'd only buy into that idea if there was some reason for it.
One last thing: I don't know where you guys came up with that piece of music, but it is just perfect for this game. It sounds like the sort of thing that would be playing on a radio listened to by space hobos.
Oh, and I see the rating's been stepped down to Teen. Good call.
