Space Guardian

---

Unity · C# · Undergraduate class project

A top-down space shooter I built in Unity with C# for a game development class as an undergraduate. Waves of enemy ships fly in along set paths and fire back while you dodge and shoot, and the game keeps score across a start menu, the game itself, and a game-over screen.

How to play

• Click the game first so it can read your keyboard.
• Move: arrow keys or W A S D
• Fire: hold the space bar

What I built

• Player movement kept inside the camera's view, with continuous fire while the button is held.
• Enemy waves defined as reusable configurations (ScriptableObjects) that set each wave's ship, flight path, count, and speed.
• Enemies that fire at random intervals and explode when they're destroyed.
• A score that carries across scenes.

In 2026 I upgraded the project from Unity 2019 to Unity 6 so it runs in the browser, and fixed a bug where the health counter dropped when you hit an enemy instead of when you got hit. The browser version plays without sound.
