Description (written by the developer; not a statement by this register)
One of your friends is not your friend. Every round at the Grinwood Fair, one player is secretly an alien wearing a normal avatar like a costume. It looks and walks like everyone else until it unzips its head and a monster pops out to eat you. INNOCENT: Collect tokens, stay with your friends and watch who goes quiet. If you hear a zipper, run. EXTERMINATOR: You have one blaster and one shot. Find the alien before it finds you. Hit an innocent and you lose it. ALIEN: Blend in, pick people off one at a time and don't get caught mid-unzip. Spend tokens on crates to unlock monster heads, unzip effects, blaster skins and pets, then trade them with other players. Rounds are quick, so jump in with friends and see who you can trust. Like and favorite to help us add new maps and heads!

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.

Monetization — game passes

Badge funnel
How many players have ever earned each badge — a proxy for how far players get before they stop. Steep drop-offs mark where a game loses people. Win rate is the past-day share of players who earned it; categories are assigned by a language model from each badge’s own name and description.
