GHOST MAZE SHOOTER You wake to dust on your tongue and the sound of footsteps not your own. Find the keys. Find the exit. Try not to be found first. Ghost Maze Shooter is a first-person horror maze runner. Every level reads as a puzzle of "which weapon do I bring, where do the ghosts come from, and how do I get out alive?" WHAT'S IN THE GAME โข Hand-built chapters with their own atmosphere, enemies, and boss endings. New chapters added in updates โ included in the same purchase. โข Three weapons โ Pistol, Uzi, Grenade โ and a single-slot inventory. Picking up a new weapon drops the old at your feet. โข Four ghost types: Patrollers stalk fixed routes. Chasers swarm. Watchers stare. Hunters cannot be killed by gunfire โ only by the grenade. โข Boss fights every tenth level โ folkloric horrors with their own powers and stories. โข Ghosts manifest from the walls, drop from the ceiling, and crawl from the floor. Look every direction. Trust nothing. โข A live combo system that rewards rapid kills. Score persists per level โ chase your own high score. โข Original ambient soundtrack. Lights flicker. Fog drifts. The walls are darker than they should be. THE RULES โข Walk silently. Sprint loudly. Loud players draw faster spawns. โข Bullets won't stop a Hunter. Don't try. โข Doors lock until you find every key in the level. โข Beat the par time without taking a hit to earn three stars. CONTROLS Twin-stick first-person. Left stick moves. Right stick looks. Tap anywhere to fire. Designed for thumbs. SETTINGS Music + effects volume sliders. Toggle film grain, screen flicker, and haptics. Reduce Motion is honored automatically. Built for accessibility. PREMIUM UNLOCK The first 5 levels are free, forever. A one-time premium unlock opens the full game โ every chapter currently shipped, plus every future chapter we release. No subscriptions. No ads.

Verdict
The clearest difference is in-app purchases: GridSum at none against Ghost Maze Shooter's 1. GridSum also leads on update cadence (daily vs every 4 days). Ghost Maze Shooter's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
