Destroy the invaders but the bullet must match their colour.
- Tap / Click on either side of the launcher to move it.
- Wait for the launcher to be the right colour and tap it to launch a bullet.
- If the bullet hits an invader that is the same colour the invader is destroyed.
- If the bullet hits an invader that is a different colour then all the invaders will speed up.
- Destroy the invaders before they land on the launcher.
- There are sound effects but no music.
- Your browser settings might block the sounds without alerting you to it - especially on cell phones.
