A simple sprite sheet workflow for small game prototypes

When a small game prototype starts to feel playable, the next bottleneck is often not code. It is usually the asset loop.

A quick workflow that has worked well for me:

1. Keep every frame as a separate PNG while iterating.
2. Name frames in animation order, such as idle_001.png, idle_002.png, and run_001.png.
3. Check the full sequence before importing it into the engine.
4. Export a single sprite sheet only when the timing and frame order are stable.

For that last step I use Sprite Sheet Maker. It is a lightweight browser tool for turning animation frames into clean sprite sheets without setting up a heavier art pipeline.

This is especially useful for quick tests in 2D games, pixel art experiments, jam prototypes, and small engine demos where the goal is to validate movement before spending time on final art.

The main rule is simple: keep iteration loose, then make the sheet only when the animation is ready to test in context.
