Read full descriptionHide full description
Grow your own penguin village in the Antarctic - a cozy pixel idle game. [Mine the Ice] Tap the ice rock and your penguin swings the axe. Every tap stacks more ice into your store. [Merge the Ice] Tap two matching pieces in the ice store and they merge into a higher tier. Soft Ice to Hard Ice to Crystal. Three tiers to merge! [Build Igloos] Tap once to pour your crystals into an igloo. It rises floor by floor, and when it's done a new penguin moves in and the village grows. [Penguin Dex] Every new penguin joins your Dex. Collect all 7, from the tiny penguin to the golden one and the legendary rainbow penguin. Tap a penguin walking around town and it will say hi. [Upgrade and Idle] Clear quests to earn fish, then spend them at the shop on pickaxes, auto-miner penguins, bigger storage and defense walls. With auto-miners on duty, ice keeps piling up while you're away. A polar bear shows up now and then - tap to chase it off and grab a reward. Under a sky that shifts from morning to day to sunset to night, with auroras overhead, take your time and grow your little pixel penguin town. No sign-up, no in-app purchases. Just tap and build.
