Today’s free iPhone app at FreeAppADay.com is Critical Wave, from Grannies Games.
The game is a dual stick shooter, available to play in three gameplay modes – Easy, Hard or Custom. Easy and Hard are obviously different difficulty levels, while Custom allows you to customize almost every aspect of the game to your own personal preferences. You’ll be able to pick which level you start at, choose to fight only standard enemies, or only bosses, unlock all of the game’s upgrades and more.
Gameplay sees you piloting your ship around colorful environments using the left virtual analog stick, while you touch the bottom right stick to shoot. The game features auto-pause, causing the game to pause instantly if both of your fingers ever leave the screen (should you be interrupted for whatever reason).
You’ll be able to fight several types of enemies, and bosses that continually grow each level. As you go, you’ll be able to access multiple upgrades and power-ups, and track your score via the game’s online and local leaderboards.
Critical Wave has been called one of the best dual stick shooters on the iPhone, so make sure to download it while it’s free today.
