I want to play it so bad (even though I haven't played the original), but the ZIP file's acting up.
Looking at your Kb size, I think you might have forgotten to put the level in or something... Mine says the archive is empty so I think that's what it is, but if I'm wrong, someone please correct me!
EDIT: to answer your screenshot question, I'm using the Steam Version of VVVVVV now, so I just use the screenshot shortcut (I can't remember what it is off the top of my head), upload to imgur and then direct link to the picture.
If you don't care too much and just want some screenshots on a mac, it's command-shift-4. Then you select an area and BAM. Looking up how to do it on a Windows 8, there seems to be a command (Alt-PrtScr) button that'll take just one window. In Windows 7 and below, there's a program called Snipping Tool you can use.
Whatever program you're using to take pics and upload them, the last two steps are the same. You need to upload to some image-sharing site (I use imgur cause it's "hip" idunno use whatever you want), and then copy paste the direct inbetween the image tags. After that, image!
As always, correct me if I made a stupid.
