Clean and easy, but very boring after more than half an hour. This is easy to trade back in.
You play the role of a teenager named Jim in a futuristic world, out on a quest to find the legendary Treasure Planet. After Jims grandfather finds evidence that it exists, you must compete in a race (metaphorically) through the galaxy to get there first.
The game itself consists of four worlds, broken up by various in-game mini-games (such as finding generators in mines) and three solar speeder races, where you must beat the clock to a set number of laps round a course.
The worlds are mainly big expanses of space with bonus and collectables in them. Occasionally you are helped by radio messages from Jims grandfather, explaining abilities and secrets. The annoying thing about them is if you already know them they're unskipable, which slows down the gameplay a lot for people who just want to get into the action.
Beating the worlds means completing goals and tasks, ranging from finding powers cells to starting generators to raiding pirate camps. Take your pick.
A small amount of the game is spent using plasma, a timed power up for gyms laser. It is used for hitting switches to open doors and move objects.
The worlds themselves seem to have a closed-end setup which curves back on itself with a start point roughly near the finish. Getting between the two poses the challenge; usually it means going right around the outskirts of the level and using as much space as possible. this makes for very long and boring levels, relieved only by the sensation of finally reaching the finish. (Wouldn't it have been easier if you could glide for longer?)
Passing between levels is done by a display aptly named the HUD, which allows progress only if certain tasks in the previous level have been completed. Some times you will need to complete one thing to start another, such as in the boss levels. (A boss token is needed to fight the boss and to get the token you must beat another level.) The positive about this system is that if you have done the right things you may be able to skip levels.
The bosses themselves are very easy at the start to extremely hard at the last boss. The game hasn't much to play for and will get boring quickly, so it can be a temporary addition the could be useful for trading other games out.
