An offline arcade reflex game for iPhone and iPad.
A balloon drifts at the bottom of the screen and everything else is falling towards it. Drag your shield to sweep obstacles away — but hold still for three seconds and the run ends. ZUPI is about continuous movement.
Blocking charges the shield. Spend that charge as a Pulse: a shockwave that clears the field and is the only thing that breaks armour-plated obstacles, which pass straight through an ordinary block.
600 levels across six worlds, all playable offline, in 50 languages.
