Wildwood
Email ccreight@usc.edu and I'll get back to you.
If you're reporting a problem, it helps enormously to include your device model, your iOS version, and the level number you were on.
Wildwood syncs through your own iCloud account. Check that iCloud Drive is switched on in iOS Settings, under your name → iCloud, and that you're signed into the same Apple Account as before. Progress should reappear within a minute or so.
Open Settings → Restore purchases in the game. Purchases are tied to your Apple Account, so make sure you're signed in with the one you bought it on.
Every board has words tucked into it beyond the ones listed. They're never required to finish a level — they're a bonus for anyone who keeps looking. Finding them all earns a third leaf.
If your region shows a consent form, there's a Manage privacy choices row in Settings. For tracking, use iOS Settings → Privacy & Security → Tracking.
Settings → Start again. It clears everything, including the synced copy, and it can't be undone.
