How to Play Ozma Wars (set 1)
Quick start
- Move beneath an approaching enemy.
- Fire upward while avoiding its shot.
- Watch the energy reserve as the wave changes.
- Reach the mothership docking interval to replenish energy.
Controls
Move Left/Right and use Fire to shoot upward. Energy falls with time and drops sharply when hit. A mothership periodically docks to restore it; the run ends when the reserve reaches zero.
Ozma Wars (set 1) — About this game
Ozma Wars (set 1) measures survival with an energy reserve instead of separate ships. Energy drains as the fight continues, and an enemy hit removes a much larger portion. UFOs, meteors and other formations demand changing firing positions along the bottom of the screen. Periodic docking with a mothership restores energy before the sequence resumes, making that meeting a chance to recover from losses rather than the end of the run.
