Hi! I'm the developer. Here's help with the game, and how to reach me if you're stuck.
Go to Menu → Studio → Add from Photos. The game finds the faces in your pictures automatically, then just give each one a name. They'll show up as invaders and get announced as bosses when they appear. There's a step-by-step walkthrough here.
They stay right on your phone. The game has no photo-library permission at all, so it only ever receives the individual pictures you hand it through the system picker. The face-finding happens on your device and nothing is uploaded — the long version is here.
Gems are consumable, so there's nothing to "restore" like a normal app unlock. But if a purchase charged you and the gems never showed up, email me the date it happened and I'll get it sorted out for you.
Nope. None at all. You can buy gems if you want to move faster, but everything in the game can be earned just by playing.
There's no account and nothing personal on my side, so just deleting the app wipes everything on your device. All I keep is anonymous, lumped-together gameplay stats that can't be traced back to you.
Email me using the button below and tell me what happened. Your device model and what you were doing at the time really helps me track it down.
Real emails go to a real person (me). I read every one and try to reply quickly.
