The game has potential due to the look of the UI and the game itself. Unfortunately, when I tried to play it, I didn't understand what I had to do, so I read the game description and learned the controls (although I didn't understand exactly what Left Shift does).
When opening the game, a screen appears with a timer and some targets (which I move with w,a,s,d), but unfortunately I didn't understand how to play this game.
Also, as long as the timer reaches zero, the game does not stop.
