The short version: Spend more only after a focused test turns the most expensive uncertainty into evidence.

A production budget should buy a decision, not simply more content. Before expanding scope, identify the uncertainty that could invalidate the project: do players understand the loop, does the first session create a reason to return, or can the team produce the core content at an acceptable cost?

Steamโ€™s Playtest feature provides a separate child app connected to a main game. It can let a team gate access, gather feedback, and deactivate the test without treating unfinished work as the final store product.

Plan the test like a milestone

Define the audience, build, success signal, and stop rule. Ask a narrow question and capture the session context. If the test shows confusion, change the onboarding or mechanic before adding features. If it shows a weak promise, revisit the concept before polishing the edges.

Do not confuse signups with validation

A signup measures curiosity. Completion, replay, explanation, and observed behavior tell you more about the product. Keep marketing interest and design evidence in separate columns in the decision log.
