About This Demo

Every card can be used to attack or defend!

Soul Gathering is a roguelike deck-building game where you fight with cards that wear down with each use.

Will you use a card in your hand to attack, commit it to defense, or save it for later?

As you progress, you must think not only about defeating the enemy in front of you, but also about what to keep for the battles ahead.

No mana and no costs!

You can play every card you draw during that turn. Combine red Attack cards and blue Spell cards to launch an all-out offensive or strengthen your defenses.

But just because you can play them all does not mean you should.

Enemies act multiple times during a turn. After each action, reassess the situation and decide which cards to use and which to keep.

Run out of cards, and you lose—even with HP remaining!

Cards have durability, which decreases by 1 each time they are used. A card disappears when its durability reaches 0 and does not return during that run.

Winning a battle restores the durability of your remaining cards. Vanished cards do not return, so the more you rely on a card, the more carefully you must choose when to use it.

If you run out of cards in both your deck and your hand, you lose immediately, even if you still have HP.

Each character changes how you use your cards!

Every time the Hero attacks, the enemy's next attack becomes weaker. Since attacking also helps you defend, you can stay on the offensive while reducing incoming damage.

For the Monk, cards used to attack return to your hand. You can attack repeatedly with the same card, but each use still reduces its durability. Knowing whether to push through with a chain of attacks or stop before losing the card is essential.

In the full game, you can choose from seven souls, including the Knight, Samurai, Witch, Vampire, and Necromancer. Their unique effects change how you plan your attacks and defenses and how your cards wear down.

Which cards will you keep for the boss battle?

A boss with unique effects awaits at the end of each area.

Will you spend cards freely along the way to protect your HP, or conserve cards for the boss and find a way through the current fight? The right strategy depends on your hand and the path you choose.

Each run is designed to be played in a relatively short time. Even after a defeat, you can keep trying different ways to use your cards and different routes.
