### 5/5 — Unique challenge

*2022-10-21*

It’s an interesting concept for a neat little challenge! The control was well implemented and thought out. I was surprised how much more difficult the 2d explore was versus the 1d metal mode.

### 2/5 — Overchallenging in practice; exciting in concept

*2017-02-20*

I don't know why I kept trying "just 1 more workaround" until I was able to find 1st 1 sound, then more.
I think I've progressed to chapter 2, but, in addition to still trying to find the details of the layout, which I assume is part of the research, VoiceOver does things I don't intend, such as double-click on an answer when I'm not even done studying the drawing, and I've been using VoiceOver on i-Devices for 3 years.  I'm currently using an iPhone SE.

I don't know what other apps give me quite this guided exploration experience, so, knowing me, I'll put up with quite a bit more frustration with this app.

### 1/5 — Confusing needs more work

*2016-07-22*

This game did not seem to explain how it was played
I was very confused even in training
I didn't know if the challenge was choosing the dots at the end or how to move my finger on the screen to select the dots for the melody
I do not like this game because it was just so unclear as to how to play
I felt frustrated and if I did figure it out I wouldn't know otherwise it was not very exciting I recommend a much better tutorial in the beginning and less screens to go through in order to play the game every time it is tiring game is too fast too easy

### 5/5 — This is fun and free

*2016-05-09*

I love this app. You really have to think about what you're doing. It really challenges your hearing skills.

### 5/5 — An ace game

*2016-04-14*

This game is ace and I love it thanks for making it accessible for people like myself who are visually impaired
