Venture a difficult journey through space to save the galaxy from invasion.

Slide smoothly to avoid crashing into space rocks and dodge enemy ships and their shots.

Tap the screen to activate your weapon, but don't forget to keep an eye on the gun heat bar and give it time to regenerate after intense shooting. Pick up new weapons, score points or find extra lives in dead enemy boxes — or choose to not pick them and save the current weapon that you have — it's up to you.

Use your total or highest score to upgrade ship or gameplay — a bunch of enhancements is available, such as more lives or activating a force field while using laser gun. Choose upgrades wisely, and they will help you progress through the game and prepare for facing the Boss.

There are 4 weapon types, 8 upgrades and endless variety of enemy types and behaviours. Take a challenge, achieve a high score and share your results!
