Read full description

Neon Spire is a one-tap tower builder with a single rule: tap at the right moment. A glowing block slides across the screen. Tap to drop it. Land it dead-center and the block stays full size. Miss, and the overhang is sliced off and falls away, leaving you less room for the next one. Five perfect drops in a row triggers FEVER, slowing everything down and giving you a window to build a run. HOW TO PLAY - Tap anywhere to drop the block - Perfect landings keep your tower wide - Every miss makes the next drop harder - One run takes about 30 seconds FEATURES - One-tap controls, no tutorial needed - Plays entirely offline - No forced ads between every round - One-time purchase to remove ads permanently - Free to play Built by 10percent studio.
