Alienzix

Retro 2D fixed shooter with several difficulty levels.

Key features
- 4 difficulty levels
- 26 levels in 6 sections
- 30 weapons
- Weapon evolutions. If you take the same weapon twice, it evolves into a more powerful one.
- Descending bonuses give you weapons, lives, shield and extra satellites.

The goal of each level is to destroy all the objects that shoot at the player while avoiding their shots, flying enemies and the walls. In a pinch, use the Hyper-Gravitation to reverse the enemy bullets back at them. This consumes energy which you gain by defeating the enemies.
