This game lacks excitement, sense of progression, and ease of controls. Jim jumps too high and although I understand the need for a the slow movement (being that Jim IS in space), the game is set up that you can't stop moving for even a second until you lose by the bottom of the screen catching you, and all that rushing guarantees that you get killed by the UFOs that sit right on top of needed platforms to survive. Judging by the 2nd achievement that is worth 100 points just to beat the game, the game must be VERY long, which doesn't do it any good since it drags on, calling forth the wrath of boredom and longing for better development of the game's mechanics. The plot line was also very poorly developed, only being a short dialogue between two astronauts. I have NO idea why they are in space, why their spaceship blew up, and why aliens have chosen to "pick" on them as they make their way to a space station. The background was pretty bland, something some comets, planets, and perhaps other space craft could've fixed. Overall, the game lacks the elements to call this game "decent," and I feel that my score is what it earns.
