How to Play

Tap on the screen to shoot towards a direction. You must destroy all visible aliens in order to advance to the next level and unlock more weapons, upgrades and aliens. For each upgrade, you can read the in-game instructions and you can upgrade all weapons for more effects, or even unlock new ones.

Tips for Beginners

Do not rush the first attempt; learn movement, timing, and obstacle behavior before chasing a high score.
Watch enemy movement, track curves, or hazard timing for a few seconds before committing to aggressive moves.
Short retries are part of the loop, so treat early mistakes as practice instead of failure.
