5 stars: The main thing that I notice with this app is that the illusion effect work better if I look at something further away rather than near by to get the best results after staring at the presentation. So it may require not always following the instructions to the letter, My conclusion,,,this is REALLY COOL! Five stars from me!!!
4 stars: I really like this app, it does work when you follow the instructions. The only issue I would like to bring up, is maybe add another warning that people shouldn't be using it for long periods at once. I feel like kids particularly those who wear glasses may damage their sight. Other than that great app. I rate it 4 out of 5.
5 stars: This I the best optical illusion app out there. The only thing is the ads distract you but to get rid of them do this. Close the app completely. Then turn off Wi-Fi and Mobile Data. Finally restart the app and bam no ads. And it didn't cost a penny. P.S. This method also works for most apps with ads.
5 stars: I love this app . I stared at the circle of the screen for 30 seconds then looked at a piece of paper and it looked as if it was moving . It won't work if you look away or blink so be careful so that you don't Do that. Try it then look at your fingers and it's amazing. No ghost pops up onto the screen and I'm glad about that. Well done for creating this app ,it truly works. For all the haters that hate this game ,maybe you looked away or blinked but don't say bad things about this app ca...
