Space Invaders

/// Getting started

1. 01Install Space Invaders from Google Play or the App Store (where it's called Starfall Siege) and open it. No account or sign-up is needed.
2. 02Pick a difficulty: Easy, Normal, Hard or Insane.
3. 03Touch the left half of the screen to move left and the right half to move right. Your ship fires automatically while you're touching the screen.
4. 04Clear every invader to finish a phase. Every fourth phase is a boss fight — beat it to warp to the next world.

/// How do the controls work?

Touch and hold the left or right half of the screen to move. Auto-fire is on whenever you're touching the screen, so there's no fire button.

/// How do I get on the leaderboard?

Sign in to Game Center (iPhone) or Google Play Games (Android). Your best score and phase for each difficulty are submitted automatically under your Game Center or Play Games name.

/// I bought a skin on another device

Open the spaceship selection screen and tap Restore. Use the same Apple Account or Google account you bought it with.

/// Is my progress backed up?

Settings, unlocked phases and skins are saved on your device. Purchases can be restored on any device; leaderboard scores are stored with your Game Center or Play Games profile.

/// How do I delete my leaderboard data?

Email us with the subject "Space Invaders Data Deletion" and we'll remove your profile and scores from our servers within 30 days.
