Write to jays1vlog@gmail.com with your phone model and the game's version (Pause → Settings shows it). We usually answer within a few days.
Purchases are credited when Google Play confirms the payment. Keep the game open for a moment, or close and reopen it: the game asks Google Play for unfinished purchases at every start and credits each one exactly once. A pending payment (cash, bank transfer) arrives when it clears. If it still has not arrived after a day, write to us with the order number from your Google Play receipt (it starts with GPA.).
Open Pause → Essence → Restore while signed in to the same Google account. The Founder's Gold finish comes back (EVOLVE → Look → Finish). Essence packs are used up when bought and are restored only with your save (see below).
Payments are handled by Google Play; refunds follow Google Play's refund policy (support.google.com/googleplay/answer/2479637).
On your phone only (there is no account). If Android backup is on, Android can bring the save back on a new phone. Uninstalling the game or clearing its storage deletes the save.
Co-op connects your phones directly to each other. Some mobile networks block direct connections; try with one or both phones on Wi-Fi. Both players need the same version of the game. For Same Wi-Fi, both phones must be on the same network and both pick Same Wi-Fi.
Only the birds in your room: the friends you gave your room code to, or players on the same Wi-Fi who chose Same Wi-Fi. They see your bird, its name and where it flies. Details are in the privacy policy.
Lower Pause → Settings → Graphics. The game also steps its quality down by itself when the phone cannot keep up.
