Spaceman 2023 is a physics based shooting game that takes place on the imaginary planet full of aliens who are not going to accept human intruders. Playing the role of the human Spaceman, you will have to use the weapons to eliminate all the aliens that you see on the platforms in each level of the game. The fun of the game play continues for a rather long time as the game features 30 distinct levels. Every new level of the game will come with additional difficulties, which should not be a surprise.
