Yes, this is the first work of a newbie, and it shows. It's extremely rough around the edges and really could use a lot more detail and backstory. Then again, Vigilante doesn't aspire to be anything of import. If you're expecting Photopia or The Moonlit Tower, here, well, why would you?
The game is complete and winnable, which beats all the IntroComp games and nearly all SpeedIF games; so when you look at it from that perspective, you can at least enjoy it. Playing time is less than two minutes, and the plot consists of simply shooting everyone who stands in your way. Seen from the perspective of the "world is against me" typical to vigilante movies, there's some catharsis in wiping out your foes.
Anyhow, I can't really say that this game deserves more than one star, but I would like to encourage the author to give it another shot (pun intended).
