Use a lighter tool for lighter game goals
ShortGame is not a full engine replacement. It is game development software for fast H5-style drafts and small playable tests.
That is useful when the project only needs a browser game, a mechanic prototype, or a simple playable concept before heavier production starts.
Treat it as draft software, not a full production stack
Use it before a larger build, or when the final deliverable is a lightweight web game people can open immediately.
Treat it as draft software for proving the loop, controls, and instructions, not as a replacement for every part of a studio pipeline.
A better first prompt
A strong prompt names one main mechanic and one clear outcome. For example: "Prototype a puzzle mechanic before deciding whether it needs a larger engine project." Add details that affect play: who the game is for, how long a round lasts, what players collect or avoid, and what should happen when they win.
