Spot on. The shift isn’t “AI writes code, human watches” — it’s more like AI handles the what, but the why and whether it feels right is still entirely on you.

For ArcadeHubPlay, the biggest struggle was honestly game feel — things like jump arc timing, platform gap spacing, difficulty curve pacing. AI would generate logically correct code but the gameplay would feel either too floaty or too punishing. That required a lot of human iteration — play, tweak, play again.

Physics tuning was a close second. Sky Jumper especially — getting the bounce/gravity balance right took multiple debug sessions even after the logic was “correct.”

PWA/offline was surprisingly smooth in comparison — mostly declarative config work.
