Quick Gameplay Overview
(for those who like to jump straight in and figure it out as you go)

Use the arrow keys and the ?️ button ('Z' if using a keyboard) to explore, select cards, and fight.

The other button occasionally used is ❎ ('X' on a keyboard) to cancelundo.

Defeat all enemies to advance the story and unlock new scenarios, as well as upgrades to your ability and modifier decks.
You are 'exhausted' and fail a scenario if you take too much damage, or if your deck runs out of cards (each time you've played all the cards in your deck you reshuffle them, but a random card is 'burned' and not available for the rest of the scenario).

If you would take fatal damage but have cards in hand, you will instead 'burn' a random card to block the damage, but beware: this shrinks your deck so you'll have limited turns left to win the scenario before becoming exhausted.

The game should automatically save your progress after each scenario, success or failure, allowing you to come back to it later on the same device (you can retry the same scenario multiple times and earn XP even on failure).
If you're not sure what happened in combat because a lot of text scrolled by quickly, at the end of any round you can press ❎ to scroll back through the message log.
