A birb that grows into something cosmic
Birb starts small: you are a plain bird eating popcorn, and every peck pushes you toward new forms. The idle side keeps running while you do other things, so the nest keeps producing and your upgrades keep stacking. The game leans into dark fantasy and Lovecraftian themes as you mutate from a humble birb into a cosmic force of nature, with hundreds of upgrades and skill trees to work through. A prestige system lets you start over and keep pushing the numbers higher, which gives the run some long-term shape.
Playing together with friends
Online Co-op is supported, so you can link up with friends rather than grinding alone. The park shows other players moving in real time, and you can chat with the flock while you play. The global leaderboards track Popcorn Eaten and Fish Caught, so there is a shared target to chase even when you are not in the same session. The social side sits alongside the singleplayer progression rather than replacing it.
Expeditions, fishing, and the nest
When you want something more active than watching numbers climb, step through the portal into roguelite expeditions. Procedural dungeons generate fresh layouts each run, with unique enemies to fight and bosses at the end to test your build. Combat plays out in an RPG style, so your upgrades and skill choices matter on these runs.
Back home, the Moonlit Waters offer a break from the chaos. The fishing minigame lets you cast for dozens of fish types, each with rarities, shiny variants, and weight records to log in your Fishdex. Your Aquarium holds your best catches, and you can trade fish for buffs. The nest itself unlocks passive bonuses, automation features, and companions like the Seagull, Parrow, and Sparrow to help things run while you are away. The whole package uses a retro pixel art look.
