Going into this game the Gameplay will seem fairly simple. You go through each level collecting yellow dots and dodging numorus enemies. But it gets Harder. Your spaceship runs on a limited amount of air which acts like the ships fuel. You can replenish this air by visiting stations throughout the levels, but you have to look hard to find them. On top of all that you must get through each level without running out of fuel. You can lose air in many different ways, one way is to run into the many varieties of enemies in the game, and another is by running into obstacles, like spikes and balls.
