Not bad, but overdone
Lets start analyling every part of it. The modifications you did to the original Newgrounds pre-loader were cool, although the play button didn't show up, it only showed when we highlight it. And I like the original colours of the tank better than those shades of green.
The background music was nice, it matches with the computer theme. Most of the error messages were funny, specially the errors that were a continuation of the other error. However, some of the errors weren't that funny, and some of them I wouldn't even consider an error (like one of the earliest ones, error #3).
The variety of icons was pretty good, I liked them. What I don't undestand is the change between the layout of the error messages. I mean, changing from a older version of Windows' error message to a newer one out of sudden.
Still, Windows parodies are way overdone here. And yours didn't have anything too new or interesting for me to go back here and play this again. I've seen better parodies than this one, which weren't just error messages, but a simulator of Windows completely. So why not trying a Windows simulator, not just error messages?
Something that you should also improve on are the buttons. They were a bit complicated to press. Also, in the last error message, the next button was still there, and it was "pressable", but nothing happens when we press it. It should go to a credits screen, in my opinion.
There's a lot to improve here. Come up with more messages, something more interactive rather than just error messages. Nice attempt, don't give up!
