I’ve spent what probably amount to a little too much time playing this puzzle. If you have a little free time on your hands I highly suggest it. I won’t try to describe it here, because the game explains it way better than I could in words. But know this: Z-Rox is not your typical puzzle, it’s very unique, so I highly recommend giving it at least a cursory glance. And know this too: if you manage to work your way up to the 59th level and beat it, please drop me a hint here or in a private message using the contact link at the top of the page. I am stuck and would be forever in your debt. Or at least until I find something more constructive to spend my free time on.
Incidentally, Newgrounds, the site I found this game on, is filled with fun time wasting games (and mentioning this site allows me to add this post to my Reviews category guilt-free) . A rare few are much better than others. Tentacle Wars is another great not-your-run-of-the-mill game. (but beat level 59 of Z-Rox for me first).
