Excellent, but buggy

This is a 5-star concept with beautiful execution. It’s the perfect puzzle game in many ways, especially working so well without over-instructing, introducing new functions in a way that is just challenging enough to figure out before going on to more complex puzzles. There are two major buggy area. 1. The music. I like it, but it full of static most of the time, so I have to turn it off. 2. The bouncing ball often just bounces itself to the right even though I haven’t touched the screen. It eventually kills itself so I can start again—and hope it works. The developer doesn’t offer any feedback possibilities in app or on web, so I thought I’d give details here. I love the game and still recommend it to anyone who likes untimed puzzles that require attention and logic.

Great game!

I originally played this game online for PC and was excited to see that it was on the App Store as well. The only problem with the app was that the sounds were completely messed up. It sounded like my speaker was broken and what was supposed to be peaceful piano music sounded like a hungry swarm of bees. I know my speaker isn't broken though because all other sounds in other apps work just fine. But other than that it's a great game.

My favorite game on iOS

It combines gameplay challenges with logic puzzles, lets you stop and come back later to same level - and very intriguing how the puzzles build on each other. Only gripe is that it takes over the ios audio stack and i cant listen to a music app in the background, even if the game sound is muted. But that's just an inconvenience; regardless this has replaced crosswords and other puzzle types as my daily 'wake up the brain' challenge.
