Let's take 'em one at a time, just because this seems to be "post your comments" time, also because I haven't slept and still have ten hours or so to go...
The first one was kinda funny... hmm. I've seen better ascii art, but having a nuke labeled "TTYL" makes up for it.
The second one, I have already seen. Many times. God knows why. At least, I hope so.
I clicked "bunny" away after thirty seconds or so because I could not stand the music.
The one below that, I have never made it past the first minute. I just don't like it.
Couldn't be bothered with newgrounds.
Finally, Bob's two ones. Or is that one twos? Anyway, I was hoping for some kind of point throughout the first one. I found it very weird to hear the theme of the original F-Zero level "Mute City" at the end of it. And no credit was given.
The second one, however, was sheer greatness. I can't wait to show that one to my sis when she comes home for the christmas vacation.
