Pyxel is a lightweight 2D game engine that the tutorial uses to demonstrate core shooting mechanics. The article, published on DEV Community and hosted on Dev.to, walks readers through adding a simple BulletSprite class, defining a constant for bullet speed, and implementing firing logic triggered by the space key. It explains how to manage multiple bullets with a list, update their positions, and remove those that leave the screen, ensuring efficient memory usage.

The code snippets illustrate how to draw a 2×2 square for bullets, move them upward at 270 degrees, and reverse the ship’s direction when firing. By processing the bullet list in reverse order, the tutorial avoids index‑shifting bugs that can occur during removal. The final section presents a complete, runnable example that combines ship, asteroid, and bullet sprites into a cohesive shooting game.

This step‑by‑step guide is valuable for developers learning Pyxel or those seeking a concise reference for sprite management and input handling in 2D games.
