ROBOT-SB -- Retro One-Bit One-Tap Space Battle

RETRO-SB is an endless scrolling retro arcade pixel-style space battle shoot 'em up (SHMUP). BUt it's not your typical vertical shooter - it's as much about dodging enemies and avoiding obstacles as much as shooting the aliens. Good for both a quick casual pick-up game or for long endurance bullet hell shooting sessions. * Endless vertical scrolling retro arcade shoot 'em up. * Simple one-tap controls, five alternate control schemes available. * Many upgrades to increase your ship's firepower. * Endless difficulty progression. * Challenging boss battles. * Achievements and leaderboard. * Vibrant 1-bit color pixel graphics throughout! ;) * Works well on both phones and tablets of any size.
