I waffled a bit on whether a demo was ultimately a good idea, but after getting so many requests I couldn't possibly turn down the awaiting public. The demo is now available here.
The demo will take a few minutes to complete, but the full version's story will take you about half an hour and can be replayed for several different endings. The full version also includes the Treasure Hunt mode with randomly generated levels and scoring system. If that weren't enough, you also get a cool retro manual to go with it, and I know how much you love reading manuals!
As usual, the full thing can be purchased at Icarus.jvscott.net.
