Not terribly fun. The necessary continuous mouse clicking kind of kills the fun factor. Plus, the fact that a "killing machine" can be so inaccurate with a gun? Heh.
Crusader, you shouldn't rate a game low based on your inability to perform well. That's like disliking your girlfriend because you're a premature ejaculator.
Odd Psilo, there *is* no Impossible badge.
Relatively fun game. I, like others, wish the hands used for control and fire were reversed, but still fun.
And the badge only takes about 12 minutes to get. Tops. If you're not willing to put in the time to get it, you don't deserve it. =)
Bobogoobo - There are only a few bugs, and they are easily worked around. If you think you're getting a bunch, you're doing something wrong.
Anyhow... relatively fun game. Doesn't get challenging until the last few though. 4/5 because there are some bugs. (Invisible blocks?)
Funny, the last boss on The Lighthouse didn't have regen for me. Level 35 did, but I killed him on the second pass. This version is very fun though, 5/5 easy.
