1. As the picture shows below, the component linking only shows in full-screen mode.

Pic 1: In non-full-screen  mode. Player see nothing no matter how they connect the dots.

Pic 2: Only in full mode, the components are already connected.

2.  When moving the components, clicking the components (blue area) won't do anything at all. Instead, you have to  tune a little bit to see a green box(red area). Clicking the red area would move the component to the blue area. What make things worse is that you can't unselect the component. Right click sell the component with discount and help you fail the game.

Pic 3: The components reloaction works in a mystery way.

It seems like this game only works in certain screen resolution. Sadly, it is not my resolution.
