### 1/5 — Game will not even open.

*2023-08-09*

Even after rebooting my phone, I can’t get this very expensive game to even open.  Is it possible to get a refund?

### 1/5 — Does Not Open

*2023-08-04*

It worked for a couple of minutes, but now the app won’t open, even after restarting my phone.  OS 16.6

### 5/5 — Works smoothly

*2021-03-25, version 10.0*

Works smoothly, does everything you’d hope. 
Though Ideally the falling speed of the blocks would speed up quicker, as I find it a bit easy (but my lazy eye isnt too bad so it is probably perfectly designed for someone with a bad lazy eye)

### 1/5 — no good :(

*2021-02-16*

It’s 17$ for something a middle schooler could code in Java. really sadden that I wasted my money on this. I can’t even get it to work properly with my eyewear and my glasses are literally just standard red and blue. I don’t understand how this is allowed to be so expensive.

### 4/5 — It works

*2020-10-29*

It’s a steep price tag but I noticed improvement after a couple times of playing. I could feel my eyes working together finally. Hoping it will continue to improve the more I play.

### 5/5 — How far should i put my phone screen?

*2020-02-01, version 10.0*

Good app but how far should I pit my phone screen

### 2/5 — Improve gameplay

*2019-07-08*

The colors work, but there are problems with the gameplay that need to be improved before this is worth $17. 
- score does not go up if you clear more than one line at a time
- game does not speed up with higher score
- color fix: in the preview for the next block, the background should match the play field. Currently both eyes can see the preview

### 1/5 — No Setup "Wizard"

*2018-01-23*

No setup instruction.  Literally none.  There is no setup wizard and no instruction, the app is not usable as is.

### 5/5 — Thank you

*2017-12-22, version 10.0*

This is great. I have never been able to use my left eye, & at 39 had given up hope. I am two and a half weeks in, and though it is a massive challenge, I can see improvements everyday. I am so grateful to the creator of this game. Combined with lazy eye videos also watched with the red blue anaglyph glasses I have achieved so much in a tiny amount of time. Honestly this is brilliant, & needs to be shouted about from the rooftops.

### 1/5 — Useless Costly Disappointment

*2017-03-25*

I purchased this app assuming that it would be like the one I have on my PC, but I was sorely disappointed. For one, I cannot adjust colors for the left and right eyes such that I am able to see objects that should be visible to one eye and invisible to the other eye. The PC version is excellent in doing that and this app should have mimicked the PC version in doing so. Without the ability to make the proper color adjustments, I find this app useless and a pricey loss. Secondly, there is no reset button for the app game as offered in the PC version. This is an important feature when you do not have proper color adjustments and need to start over. Further, when you have to stop in the middle of a game and return later, you cannot start a new game until you have finished the previous one. Hence, you are forced to complete the game before you can begin a new one. I find that I am unable to use this app until these fixes are made. So, while I do highly recommend the PC version, I do not recommend purchasing this app for the iPhone until these features have been added and/or fixed. This was a costly disappointment.
