Fortiori

Fortiori is a deck-management roguelike about adapting your strategy over the long term. You tap cards to increase their values, but each tap raises the chance that a card will be deleted. In each round, you must score higher than you did in the previous one.

Cards and risk

Fortiori includes 80 unique buffs to collect and use, along with 75 unavoidable debuffs that disrupt your plans. An in-game shop lets you spend coins earned during a run on extra lives, new cards, splits and powerful buffs.

Bosses and modes

The game has 18 unique bosses. Losing to a boss does not end the game; instead, it makes the game much harder, while winning changes the game. In Normal Mode, you must defeat seven bosses to win. Boss-less Mode removes the bosses, while Chill Mode has no bosses or debuffs and increases the number of buffs. Six unique Challenges offer another way to play.

You can choose from nine playstyles, which change the game and call for different strategies; any playstyle can be used in any mode. Fortiori also offers two operations: multiplication, or addition for a more controlled experience.

Date Iori

Date Iori is a dating sim where your dialogue choices and gameplay skills determine whether you get dumped or picked. It features branching dialogue and eight unique endings. Its save file does not affect the main game's save file.

Music and changes

Fortiori has gained new game modes, quality-of-life additions, artistic changes, user-experience changes and balance adjustments over time. The description also presents Multiply, Collapse and Stack again as parts of the game's past.
