Gull Tower

Collect feathers, carry on from where you fell. Four characters, an endless tower, one rule — don't fall.

You're a grumpy seagull trying to get back to Galata. Ahead of you: the apartment blocks of Istanbul. Behind you: a screen that never stops rising.

Jump, bounce off the walls, somersault. The faster you move the bigger your combo, and the bigger the combo the higher you climb. Your only enemies are gravity and the screen itself — fall behind and it swallows you.

• One finger. Hold and slide, that's the whole control scheme • An endless tower, different every single run • Combos built from wall bounces and mid-air somersaults • Four characters: Ayaz, Fiko, Muhsin and Bahtiyar • Breaking awnings, swinging clotheslines, sliding satellite dishes • Died at floor 87? Carry on from exactly where you fell

A run lasts forty seconds. You'll still play one more.
