We sit down with Katie Madding (CEO, emhanceAI, ex-Adjust CPO) and John
Hobson (founded user research at Bungie and Blizzard, 20+
years on Halo, Destiny, WoW). The conversation walks through
two real case studies — a Skullgirls Mobile playtest and a
creative comparison — using emhance AI's facial-emotion
analysis (0.89 ROC AUC, basically "lie detector" precision).
The findings are uncomfortable. Skullgirls' tutorial pauses
combat to teach mechanics players don't need yet. Every
level ends with 5 passive screens stacked back-to-back. And
the creatives with "near-death experience" hooks within the
first 4 seconds genuinely outperform — not because Chinese
UA teams said so, but because the emotion data shows it.
If you build games or ads for mobile, this is required
viewing.

📌 KEY TAKEAWAYS
— emhance AI uses facial-emotion analysis (0.89 ROC AUC, "lie
detector" precision) to identify exact moments of high
and low engagement during playtest sessions. Engagement
= emotion + attention combined.
— Skullgirls Mobile tutorial findings: pausing combat to
teach optional mechanics players don't need creates
frustration. Players come away thinking the game is
shallow because the tutorial fights are too easy and the
text walls killed momentum.
— John's "attention budget" rule: teach maximum 3 things
at a time, then give players space to digest. From his
Halo days: pop up a tooltip → if used, snooze 5 minutes
→ if not, repeat. Snooze 15 minutes after second use.
— The "5-stack of boring screens" problem is universal.
Win → victory animation → reward screen → loading
screen → cut scene → talking head → finally back to
gameplay. Nobody designed this stack on purpose. Real
playtesting reveals it.
— Why 6 out of 7 AI ads still suck: the concept is right
("save the character") but the small execution details
matter enormously. Emotion data lets you identify which
4 of 15 things in a creative actually worked rather than
throwing out the whole concept.
