Unfortunately the screenshot/front does not really match the game.
I think your idea was good and the game does work for me however it does not work well.
A few pointers.
Ghost moves with A and D however not with W and S however using the arrow keys does work it is a bit confusing
When switching of view either "teleport" the other character to you or move the camera to the selected character.
And one other remark. i had to use google translate to understand what you wrote, is fully in your right to only use your own language, but if you want better feedback and people to be able to better play your game a few lines in English could be helpful. Still good attempt for a week work and with some minor updates it could feel better.
