What is FACTORIZE: 1?

This 2D deckbuilding roguelite follows a boy summoned to Factorium, where numbers hold power. During each run, you collect number cards, read enemies' next moves, and combine cards into numbers. The game automatically factors each result to trigger attacks, defense, healing, or card draws, while your companion Fio's six forms change how you combine cards.

For you if...

+you enjoy number puzzles woven into card battles
+you like adapting your strategy to each hand

Not for you if...

−you want reflex-driven combat instead of turn-based decisions
