This is a well, pleasant game and I liked at the start and throughout the game that the screen was red, it really fit in with the game. =)
I really liked this game, it was very good in most ways, and challenging in others. It made me feel happy, as if I was defending OUR planet from meteors, not Mars.
The concept of this game is quite unique, and the game-play is great, fighting off meteors with a small, round turret.
I think there should be a sequel, Red 2: Defender of Earth. I would like to see in this sequel (if there's going to be one); More helpful things, other than Shield, Turret and Power power ups.I'd also like to see that you can upgrade the turret, so it can fight off stronger things, like lots of big meteorites, or aliens.
The graphics in this game is alright, but I think they might need a little improving. If you're on top of a planet, should you be seeing clouds? I think not. There should be stars in the background of this game.
I think there should be sound effects in this game, because you hardly hear anything but the slow, scary music playing.
Overall, I really enjoyed this game, it's fun, the concept and game-play is really interesting. The background fit well with the game, but the music needs improving. Rating: 9/10
