Climb a sky railway with a deck of cards. Fill the steam gauge and blow the whistle.
The Cloudrail climbs from Blossom Valley over the Storm Coast to the Ember Summit, and the line is overrun with weather spirits, rust beasts and track gremlins. Pick a crew member, build a deck one card at a time and drive the little engine Marigold up the branching map: fights, elites, shops, rest stops, strange events and a boss at the end of every act.
Every card you play adds Steam. At five, the whistle blows: the Conductor blasts every enemy, the Engineer vents pressure into Block and Thorns, the Signaller clears the line and draws two cards. Plan which card fills the gauge, read the enemies' intents, and stack relics that change how the whistle works.
Three crew members, 49 cards with upgrades, 15 enemies, 18 relics and a run that fits in a lunch break. Lose and you learn; the next climb is a new map.
Tap a card, then tap an enemy to play it. Each turn you have 3 Energy and draw 5 cards; Block lasts one turn, so watch the attack numbers above the enemies. Every card adds Steam; fill the gauge to 5 and the Whistle blows. After each fight pick one of three cards, spend gold at stations, rest to heal or upgrade, and beat the boss to reach the next act.
