Steep learning curve

The hint/tutorial system is woefully inadequate, especially on the larger puzzles. After a while it’s more frustrating than fun.

Steep learning curve

The tutorial system is a little clunky, but perseverance pays off!

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 🥲
