The boss is way too hard to beat. It would be more fun if there were more levels with easier bosses, before you meet this continuosluy shooting bastard.
I reached level 5 this time, but my newly bought defense was reset to zero by the program. Damn birds, and damn defense shield that gets reset all the time !!
I'm stuck with the collapsed robot in the last scene. The robot has a keypad on it, but there's no clue in the videotapes. Anybody who knows how to get the right code ?
