Docking Sequence is an interesting departure from the norm when it comes to mobile games, as it deals in some completely different ideas than what many casual gamers may be used to. With that in mind, it's an entertaining amalgam of space junk and steering ships that you'll want to get into so you can show off your skills.
Your objective is to pilot a small ship between space stations to make sure you get home on the very small amount of fuel you have. So what you're actually doing in each stage is completing a docking sequence. You have to learn how to specifically maneuver your ship in a manner that ensures it's able to dock successfully without touching anything. If you get hit, your ship will be totaled, but if you use too much gas to dock you won't be able to move anymore. There are 100 stages to complete, each rife with different types of environmental hazards and other problems that seek to keep you from heading home.
This is a very difficult game, and it knows it -- sometimes to an annoying degree, too. You'll be forced to calculate every single move and account for it while saving gas, and it becomes an endlessly frustrating thing as you power through the stages left in the game. It's exactly the type of game that you'll either love or hate, depending on how you play and what you look for in a game. You could potentially be spending double the amount of time on one simple level, however, and this will undoubtedly be a turnoff for many.
Docking Sequence is an entertaining diversion, but only if you're willing to experiment with different ways of solving puzzles. For everyone else, that may be a little too involved.
