The 5 dollars I spent on this game don't make up for the time I wasted playing it.
The levels are very linear and uninspired in design. Every enemy pretty much looks the same. The weapons available are few in number, and the controls don't work out that well. I was only able to go through the first three missions because I didn't want to continue, but, in the long run, you can't blame me.
They TRIED with the stupid map editor, but no matter what you do in the game, you can't help but regret buying this game. No matter how little it must have cost.
