The plain-English version
A development display of measurements or state that helps explain what a game is doing.
Why it matters
Useful overlays turn invisible timing, collision, input, and networking behavior into inspectable evidence.
Let’s make it click
A movement overlay shows velocity, grounded state, active collision shapes, and the most recent input action.
Vibe Bro’s heads-up
A debug display should avoid exposing credentials or private player data and needs a deliberate release policy.

Supported: In-game diagnostic overlays can expose statistics and state. The secret/private-data and release-policy warnings are prudent implementation advice.
