always there for me

this is one of my all time favorite games. i’m not very good at it. i dont open it very often. but its always there when i need it most, to help me quiet my busy mind. 5 stars.

Love this game, hope it stays available

This is a super relaxing game! It has beautiful graphics between levels, and relaxing music as well. I play it a lot, often when watching TV. I know they stopped updating it; I just hope it will still be available to download when I get a new iPad.

Never Delete!!

Please never delete this app, it is SO amazing for my anxiety attacks! The music, the simple but beautiful puzzles, the calming colors and sounds. This is an S tier game and I wish I could get more people to download it. Sadly all my friends have Samsung 🥲

Muito lindo

Muito perfeito, podia ter em português

LOVE: I'm a forever ilu fan

Ilu was my first Brainium game. I downloaded it after my Dad died in 2016 with Alzheimer's and I wanted to find ways to keep my mind sharp. I find that the logic activity in this game is that wonderful elusive mix of both challenging and relaxing/soothing for my mind and nerves. Plus the aesthetics and general sensibility of the game really appeal to me. Long after I leveled up to Expert and acquired all the avatars I wanted, I've continued enjoying daily play of the game while my crystals rack up for the fun of it (1.5M's on the near horizon)!

Several years later, my ilu game is still elevating. I've gradually learned how to see the puzzles' logic in new ways, continually challenging myself to wean my play away from using this or that tool or help.

Ilu's still my favorite game for hundreds of design reasons - the logic structure, the aesthetics, the levels, the tools, the daily challenge... PLUS, since it has no ads, I can make ilu a reliably good, clean, ad-free part of my daily puzzles and brain play.

I was sad to read they've made their last updates - til I realized ilu's already really kinda perfect. I hope to play it for many years to come. Everything about ilu is frankly just right for me.
