I'm very sorry you guys encountered this problem. We thought we had it fixed since last few updates -__- If you can give us any details about how it's not working so we can fix it, we will truly appreciate it. We will go back to the drawing board
To answer both your questions: Yes, it's the arrows in the keyboard. You press the arrow keys in the right order. "Right order" being the arrow keys pattern associated to the image of the hands in front of you (and using the smaller images on the left as reference).
When you do it successfully, you finish a spinning <movement>, and then it switches to a new movement (that is, the bigger image changes into another, which has its own instructions / arrow key pattern).
You finish a third image (arrow key pattern) to complete a <sequence>. After getting 10 correct sequences (3 images each) under 45 seconds, you win!
...It sounds a bit more intimidating than it actually is, I promise.
If you get the game to work for you, and want to give it a second chance, my suggestion is: don't overthink it, just try to follow what you see.
Sure, it helps to memorize what each image means in key-pressing, though not required. If you don't get nervous, you should have plenty of time to spare. (And if you do get nervous, don't worry, I'm sure you will be an expert by the third or fourth time you play it :) It's the learning curve. It's by design: it's supposed to take a few tries.)
Btw, the mini-game was my idea (I'm the writer), I wanted it to be somewhat challenging. But if it's giving people such a hard time, we will see about adding an option to skip the mini-game.
Thanks for both your inputs, and for the support. Also, sorry it took me this long to answer. I never got a notification about the last four or so comments on my mail O_o Very sorry about that. If you want to give us any more of your thoughts, you are more than welcomed. We will look forwards to that!
