Launch and the first week

Before you publish

• Thumbnails: ten ideas written first, the best two or three made. See the thumbnails guides.
• Icon: the strongest thumbnail idea as a 512x512 crop, readable at 50 px.
• Store page: name, description, genre, max players, and supported devices (phone, tablet, console). Check each device actually works.
• Products and passes: created, priced, and tested through ProcessReceipt in test purchase mode. Granted exactly once, surviving a rejoin.
• Analytics wired in before launch, not after. Custom events and funnels for the first-time flow: join, first earn, first purchase, first rebirth. Data you didn't collect on day one is gone.
• Security settings: enable "Allow HTTP Requests" only if something actually needs it.

The first week

• Read the funnel daily. The biggest drop-off is almost always in the first few minutes. Fix that before adding content.
• Plan updates from data, not from what's fun to build next.
• Write down what changed and its effect for every update, so the next decision has evidence behind it.
