What is it about?

Visually, ilu is beautiful. The game contains a minimalistic aesthetic style that's completely rendered in 2D. It uses simple shapes to represent the board and the pieces, as well as a soft color palette that is full of soothing gradients. Each of the infinite stages contains a board that lights up yellow, to represent the light in the darkness. And as you solve each puzzle, lush green life blooms and flourishes, proving to be the icing on the cake on this already gorgeous game. All animations are smooth and fluid on my iPhone 8 Plus, and the game has an ambient and atmospheric soundtrack that's tranquil and zen-like. The sound effects are whimsical and create a dynamic track on it's own as light fills the board.

App Store Description

ilu is a puzzle game.

In every puzzle, all that is dark must light up.

You place a light by tapping a dark area.

You will discover clever ways to place the lights as you play the game.


ilu is light.

You are a keeper of light.

In the vast void of space, countless lost worlds drift in the dark. Planets that have lost their star mothers and are too far and cold for the rays of starlight to warm their dark and frozen features.

It is your mission to terraform these barren planets.
As you spread light through the worlds of ilu, watch the ground light up while colorful and beautifully animated plants sprout as the entire world gently teems with life.


• Infinite relaxing logic puzzles solved with light
• Simple rules that create compelling solutions
• Dynamic music that responds to your play
• An animated & intelligent hint system that teaches & guides your way
