Once Upon A Card

Once Upon A Card is a roguelike game inspired by Slavic fairy tales. You build a dungeon through a child’s dreams by arranging rooms on a grid, creating a path and facing nightmares along the way. Each run gives you the chance to build a different deck and try new strategies.

Build your deck

You collect unique cards with powerful effects. Engaging enemies can earn you currency or add cards to your deck, and you can spend currency to expand and upgrade it. Optimize your deck, defeat enemies and take on the final boss.

Shape each run

Place rooms to progress across the grid and combine them as you work to defeat your nightmares. The game combines real-time puzzles with deckbuilding, and repeated runs let you craft new decks and strategies.
