GRID RUNNER: NEON PROTOCOL One speed. One shot. Every hazard on the beat. Grid Runner is a hard-as-neon rhythm platformer. You race a glowing grid at a constant, relentless pace while every spike, gap, and gravity flip is placed precisely on a beat of the track. Learn the pattern, feel the rhythm, and thread the perfect run. Tap to jump. Hold to keep hopping. The same touch thrusts your ship, flips gravity on the ball, pulses the UFO, and steers the wave — five distinct game modes that change how you move mid-level, right when the music shifts. FEATURES • Five music-synced levels, each mapped beat-for-beat to its own track — from the opening pulse of GENESIS to the 136 BPM chaos of MELTDOWN • Five ways to move: cube, ship, ball, wave and UFO — plus jump orbs, gravity orbs, jump pads, gravity flips and speed changes • Tight, deterministic controls: custom kinematic physics on a fixed timestep, so a run only fails when YOU miss • Portal checkpoints and credit-priced revives — push deeper, or go clean for the perfect no-checkpoint run • Earn credits on every attempt and spend them on a growing shop of neon skins • Best-run marker, level completion and live progress percentage at a glance • 100% original, code-generated visuals — no stock art, just pure neon geometry on a glowing grid EASY TO START. BRUTAL TO MASTER. Every level is proven completable — the only thing between you and the finish is your own timing. Miss a beat and you restart. Nail it, and it feels incredible. Pull on your headphones, lock into the rhythm, and run the grid. More levels incoming. The protocol is just getting started.

Welcome to Whack Stack!, a satisfying physics puzzle game where tall buildings, stacked blocks, and unstable towers are waiting to be knocked down. Aim your cannon, fire the shot, and watch the structure collapse piece by piece. Bring down every stack and clear the stage with the perfect hit! Whack Stack! is easy to play, but every level makes you think. Buildings are built with different shapes, some parts are stronger than others, and one well-placed cannonball can bring the whole tower crashing down. Look carefully, find the weak point, and smash each structure in the smartest way. WHY YOU’LL LOVE WHACK STACK! * Simple cannon gameplay: aim, shoot, and smash the stack * Satisfying physics destruction: watch towers collapse in real time * Smart puzzle strategy: find the weak point and choose the best angle * Powerful cannon shots, falling blocks, chain reactions, and more * Different buildings, stacked towers, walls, bridges, and tricky structures * Clear each stage by knocking everything down * Short, satisfying levels perfect for quick puzzle sessions * Easy to learn, tricky to master A PHYSICS PUZZLE WITH A BLAST Every stack is a puzzle.

Aim carefully, fire at the right point, and the whole structure can collapse in one satisfying chain reaction. KNOCK DOWN EVERY STACK The cannon is ready. The target is standing tall. Blocks are stacked, balanced, and waiting to fall. Your job is simple: aim the cannon, hit the weak point, and bring the whole stack down. But every shot matters. Use the right angle, the right timing, and the right amount of power to clear the stage. Can you smash every stack with the perfect cannon shot?
