About Choo Fort
Choo Fort is an idle train tower defense game: your stacked tin train rolls across the country while waves of grumpy goo gloops attack. Rescue critter crew for new turret wagons, merge them into stronger stars, pick upgrades on every level-up and blast the horde back with the giant CHOO! horn. Beat the boss at the end of each stage and upgrade your train in the Depot.
How to play
Your crew shoots by itself. Touch or mouse: tap the CHOO! button (and Rockets / Frost once unlocked) to use skills, tap a card to pick a level-up upgrade, and tap Pick up or Skip at survivor stops. Keyboard: 1 / 2 / 3 or Space for skills, 1 / 2 / 3 to pick a card, R to reroll, Enter to pick up a survivor, N to skip, Esc or P to pause.
