Quiet Gate

Quiet Gate is a top-down stealth puzzle game set in a mysterious world of shifting dimensions. You are a shadow spirit that must navigate treacherous gate mazes, avoid dangerous Noise Sentinels, and collect Silence Shards scattered across 20 unique levels.

Gameplay
Move through tile-based levels using a virtual joystick. Rhythmically pulsing Gates open and close on their own timers. You must time your movements carefully and pass through them while they are open. Making noise alerts Sentinels to your presence. Stay silent and you stay invisible.

Enemies
Noise Sentinels patrol each level and react to the noise you create while moving. If they detect you, they will chase you down. You can eliminate Sentinels with a stealth kill by approaching them from behind while cloaked, earning bonus coins and score. Every 5 levels you face a powerful dimensional Guardian boss with multiple phases.

Power-ups
Five types of power-ups can be purchased in the shop or found in levels.
Shadow Cloak makes you invisible for 5 seconds.
Void Step lets you move in complete silence for 10 seconds.
Echo Decoy lures nearby Sentinels away from your path.
Time Freeze locks all Gates in place for 8 seconds.
Null Shield absorbs one hit before you take damage.

Scoring and Progression
Each level awards 1 to 3 stars based on your score. Score is calculated from shards collected, time remaining, stealth kills, and shard combo chains. High scores are saved per level. Progress is persistent across sessions.

Achievements
Unlock 10 achievements including Silent Shadow for completing a level without triggering any enemies, Combo Master for chaining 10 shards in a row, and Void Walker for completing all 20 levels.
