Prince Rystiya's Starship is a simple 2D space shooter. It's a student project made by a student from SMU Guildhall.

The rebels claimed that they fought for freedom and democracy, yet they built a totalitarian regime instead. As a heroic imperial fighter pilot, you will eliminate waves of rebel scum and hunt down their leader.

Your ship is highly advanced. It has multiple weapons, and its shield can endure extreme damage. However, you must keep a close eye on your energy bar. Your shield, weapons, and engines all consume energy. Without energy, you would be extremely vulnerable.

> 10 waves of enemies.
> Manage the energy supply on your fighter.
> 3 intense boss fights.
> Free to play.
