Great game, I thoroughly enjoyed it! The only way you could possibly make the game even better would be do make the storyline longer, add more missions and increase the prices of the upgrades, since it's quite easy to get them. Also, you could add a mute button for players who like to listen to their music instead of the game music. The graphics overall were nice and nostalgic, and the music was nice to listen to but it never changed, which was a downside. However, I loved the game and managed to complete it fully. I will give this game 5 stars, because it deserves it! ;) One more thing, the game could have badges! ^_^
