Thanks for playing our game!
With the feedback, we noticed that we lacked instructions in the game. We will put some instructions when the voting period ends.
But the idea of this game is: try to shoot when the ghost is on screen. The ghost appears 3 times and the time on screen is increased for each time. Of course, if you shoot in the ghost the first time it appears, your score will be better.
Anyway, thanks for playing and for writing us feedback ;D. It's really important for us.
