Greetings! For the past couple of weeks I've been trying out all the hack-challenges I could dig up to get some inspiration for my own one. I have to say this is probably the best both in means of nice design, low/zero level of bullshit (thinking of the cyberc0p thing), and fun ideas. The pyramid buildup / level advancement is a nice idea as well. You did a nice job.
As for my own one, don't worry I didn't steal stuff, except for maybe the idea to have an elementary level math challenge every n levels :) Mine involves stuff like 'enter a nasa.gov url where the page referred to contains <string-generated-from-your-ip>', recognizing des/md5/base64, exploiting php by source, having a snifflog and recovering the mssql password from the session, looking up virtualhosts for ip's, those kinds of things. :-]
Eventhough as I said I only came for inspiration, I found the levels fun so i will most probably return. Again, keep up the good work.
