Classic shoot ’em up that surpised me because it’s wonderfully crafted and perfectly adapted to mobile devices.
Control is smooth and well thought; I especially like the option to drag from any point so the plane is not under your finger. Also, when you raise your finger the game slows down and that’s very useful when you need move your finger to other point, or to take your eyes off the screen for a couple of seconds, or just think of a strategy to accomplish your objectives.
Each level has 4 aditional objectives (medals) that you can achieve besides just finishing the level. If you get the four medals you can replay the level at a higher difficulty and get more medals (you need a number of medals to play advanced levels).
With the stars that enemies drop you can upgrade your weapons. Most weapons are infinite but 3 of them are limited: laser, shield and megabomb. Besides upgrading, you need to spend stars to buy units of those limited weapons, or collect them when an enemy drops one.
Although sometimes there are a lot of things on the screen it’s fairly easy to distinguish what you have to avoid (enemies and bullets) from what you can collect (stars and weapons).
All in all a perfect game you can play for free. Or pay a little to remove ads, which I did because Sky Force totally worths it.
