What do you actually do in the game? It sounds intriguing.

Hmmm this game is interesting. Been playing it and got a few correct. It is a challenge though. Good luck to everyone else.

Thre's a slight issue. After getting through the very first one where it tells you what hint you'll use, and if you get the image after that wrong, the tone won't play. Very very weird and kinda bad. doesn't help you see the points or drawing or whatever it is you're supposed to be tracing.

For you to draw, doesn Hand Writing Mode need to be enabled?

Submitted by TJT 2001 on Friday, April 15, 2016

No, you do not need to have the handwriting mode in order to use this app as it uses direct touch.

The point of the game is not to draw; it is to interpret a drawing. By dragging your finger around the screen to find lines and points, you must shape these in your mind to form an image.

This game is not very fun. It seems that this is more of an experiment than a game.

In my opinion, the usability comments should be changed because VoiceOver is required to use the app if you cannot see the screen for reading and navigating the information.

what a great concept! for those who asked, there is a column on the right-hand side of the screen and when you explored all sides of it and double tap to say you are finished, you are then asked what have you been looking at and you have to remember what you have viewed!!

Hello to all, chapter 4, whereby you are using sand to detect the points and lines is so difficult! this game is a real challenge. i do think though that you need to understand print letters to play. a v shape and a reverse v shape, plus an x, are common shapes. i am really enjoying this so far though!

I downloaded this game on my iPhone 6s Plus and I'm very new to a such puzzle game.
I highly recommend someone to record a podcast for gamers about this game and show us how it is played.

Lol. It won't be me this time who does a podcast. I can't draw and memorise shapes. I failed that part of my IQ and computer tests a few years ago. Hehahahaha!
