StealthBomber is a free, 2D arcade game in which you pilot a "stealth bomber" dropping bombs on a steady stream of tanks, trucks, and other vehicles.
You hold your device vertically (portrait, not landscape), with your bomber moving back and forth at the top of the screen and your enemies moving left to right on the bottom of the screen. You move horizontally using a touch-screen slider at the base of the screen (or just touch and drag anywhere to move), and you drop bombs with an adjacent button. A set number of enemies, all with varying speeds and toughness, move across the screen in each level, and you have to carefully time your bombs to destroy a certain number of them--without running out of bombs--to advance to the next level.
StealthBomber occasionally mixes things up (for example with bomb-deflecting whirlwinds or explosive missile carriers), but for the most part, the gameplay can quickly become monotonous--and hard to follow, given the screen's tight, portrait-mode proportions. That's only made worse by frequent animation stutters and inevitable crashes that completely erase your progress.
StealthBomber looks and sounds great, with nice audio and art direction, but that doesn't compensate for its instability and one-dimensional gameplay. The game also shows small advertisements between levels, along with a loud video ad on launch that will ignore your device's mute switch.
