The consept and the whole game idea is entertaining and amusing.
The music in game did get on my nerves and was extremly anoying, to be honest the maingame song didn't suit that kind of game but the menu song made a great buildup for the game.
The graphics on the other hand was smooth and nicely made, but what bothered me was that it said World defense on the planet itself, like we need to be
reminded of what we are playing.
Nevertheless this was an interesting and fun game to play.
