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 colorful 3D physics puzzle game where stacked materials, tall towers and unstable buildings are waiting to be knocked down. Aim your cannon, fire the shot, and watch the structure collapse piece by piece. Smash every stack, clear the site, and finish each level with one perfect cannonball. A SITE FULL OF STACKS TO SMASH Stone blocks, wooden boards, heavy crates, steel barrels and fragile parts are stacked high and ready to fall. Every scene is a new build site: stone walls, steel frames and heavy material stacks, all built to test your aim. Load the cannon, pick your angle, and blast the whole thing down in one satisfying wave of destruction. SIMPLE MECHANIC, CLEVER PHYSICS PUZZLE The mechanic is simple: aim, shoot, smash. But every stack is a real physics puzzle. Some stone blocks hold the whole structure together. Some crates and barrels only shift. One fragile piece can break, trigger a chain reaction and drop the whole stack. Shoot without aiming and the structure just shakes. Find the weak point, control the angle and the power, fire the perfect shot and let the destruction do the rest. WHY YOU'LL LOVE WHACK STACK! • Simple cannon gameplay: aim, shoot and smash the stack • Satisfying 3D physics destruction, with every block, board and piece falling in real time • Colorful destruction scenes: stacked towers, stone walls, bridges and tricky structures • Smash stone blocks, wooden boards, crates, barrels and fragile parts • Destructive chain reactions that knock a whole building down in one blast • Clever puzzle challenge: read the scene, find the weak point, fire the perfect cannonball • Fun, chaotic cannon physics with new levels and rewarding destruction • Short, satisfying levels, perfect for a quick smash session • Easy to play and learn, tricky to master EVERY SHOT COUNTS Aiming is a skill. Control the angle, control the power, trigger the reaction. Hit one fragile block and the barrel stack pops. Knock one board down and the crates follow. Clear every object, break every obstacle, and the stage is yours. Each perfect shot rewards you with new cannons, new stone structures and bigger destruction. READY, AIM, SMASH! The cannon is ready. The stack is standing tall. Blocks are stacked, balanced and waiting to fall. Aim the cannon, hit the weak point, smash the structure and clear the stage. Can you smash every stack with the perfect cannon shot? Download Whack Stack! and start your first destruction puzzle today.
