IRU is a Roguelike about building up a unique team of creatures. Explore the world by day, assemble a team and fight with it against the dangers that come at night!

IRU is full of unique and wonderous creatures, each with their own strengths and abilities!

Can you find and tame them all?

Face increasingly dangerous foes in strategic auto-battles.

Combine the strengths of your team and develop unique strategies!

Travel across diverse biomes — from peaceful meadows and lush forests to ancient lakes, and harsh deserts. Gather materials, discover new companions, and shape your team through the choices you make along the way.

With every new day, your team grows stronger. Unlock additional team slots, gain experience, and evolve your strategy as new possibilities open up. Each creature develops throughout a run and can unlock powerful mutations, enhancing their capabilities and creating entirely new playstyles.

With randomized encounters, evolving builds, and endless combinations, every run becomes its own story. And even after victory, progression continues — unlock permanent starting bonuses, experiment with new approaches, and return stronger for the next adventure.
