Devil's Gate
Devil's Gate is a platformer game where players guess trap locations on maps to avoid death, testing rationality and reflexes with each critical step.
Boo Chains takes place on a spooky Halloween map split into 5 zones. A giant boss appears every 10 stages. Players can unlock 5 monster heroes with special powers, buy upgrades, complete daily missions, and claim a nightly gift.
The core mechanic is linking neighboring monsters that share the same number or are one apart, then setting off the chain. Long chains create pumpkin bombs, lightning, and a wild ghost that explode together for huge combos. Some monsters are trapped in webs, chains, tombstones, and armor, and you free them.
Desktop: click and drag across neighboring monsters with the same number or one apart, then release. Arrow keys or WASD move, Enter links, Space collects, B activates a power, H shows a hint, R shuffles, and P or Esc pauses. Mobile: slide your finger across the monsters.
