Moon Shuttle/ムーンシャトル (Arcade, 1981, Nichibutsu)

This is Moon Shuttle/ムーンシャトル for Arcade and in this horizontal space game you have to travel through the meteors by shotting at them. Make your way forward results in bonus points, failure to do so will lose you a space shuttle but never give up as the game tells you to by reaching 20000 points to get an extra ship. After that a number of Bomb Launchers, Expandos and Men-O-War flying around shotting at you, the final enemies are Blob Men and Combrades that are hard to shot at due to them appearing in different corners. After that the looping begins until you get a game over. This is one of the first games to use a horizontal screen in the galaxian hardware which you would normally see the stars coming down, but they now come from the right side which is very interesting because no game could do that until later on making this one of the earliest examples, I think.
