Name the bar before the build
“Make it amazing” is not testable. “A first-time player can understand the goal, move, recover from a miss and tell a clean landing from a crash within two minutes” is a bar a critic can inspect.
The bar should include feel, readability, accessibility and performance—not only whether the page loads.
The critic needs the real surface
A fresh reviewer should play or inspect the rendered build, use a phone-sized viewport, navigate with a keyboard where relevant and look at the source metadata. A source review alone cannot tell you whether a jump reads at speed.
Fix the highest-impact failure, then repeat until the criteria pass. Stop when the quality bar is met, not because a round count feels complete.
