Control systems in Impossible Space are just like Archer and all the titles within this genre. All you need is your thumb to play. Move your character around the screen, so that when you stop, you automatically shoot the nearest enemy. Sometimes, depending on the improvement you make, you'll also be able to throw grenades while you're standing still.
Your objective is normally to complete a specific number of consecutive levels. After finishing the last level you receive all your rewards and can equip your characters with new weapons and other pieces of equipment. You can also customize your character with different types of armor, as well as all kinds of firearms, like guns, machine guns, and shotguns. Each weapon allows you to play one way or another, since shotguns, for example, have a much shorter range than rifles.
Impossible Space is an action game with perfect mechanics and streamlined control systems that are ideal for touchscreen devices, offering a fun game experience. Graphics in the game are also very good, with a lot of care put into designing each enemy and scenario.
