Very cool
It kinda floors me that you're the mind behind one of the lightest cartoons on newgrounds, and then you come up with something like this. Great choice in music; that really pushed the movie to the next level. I do agree with the one guy, watching a chat log generally isn't the most entertaining thing in the world, but I think you made it work. Really well, at that.
The only thing I'd recommend would be to make the kid's glasses a different color; they're kinda hard to see. Maybe up the contrast in the kid's room, too. Beyond that though, everything looks great. The chat log was well designed, loved the kid's expressions, and the timing with that final line was spot-on. Looking forward to more like this!
