I enjoyed it. Well, there is a lot of this kind of games right now... but as a project it deserves recognition.
I really enjoyed this game. Try adding more levels, I like the player levels feature. Try adding an online mode?
Not bad, kinda easy. Died 2 times during main campaign.
Awesome game. Just wish it had a restart button and that when you are done playing one of playing one of the players levels that it doesn't take you all the way back to the main menu.
