First Person Sokoban game

Hi,
if you ever wanted to experience a Sokoban puzzle from first person you should try this game. There is ingame puzzle editor so you can create your own, and add more 3d challanges.

I am a Unity hobbyist, this is my first complete unity game. I made this simpler project as practice for future more complex games. You can check it out on itch.io, it is free of course.

Here is a gameplay video.

How can i change controls?
i can rotate the view with the mouse, and “w” goes in view direction.
so i think it must be pretty easy to control with left mouse-button instead of “w”.

And how do i open the level-editor?

I cannot see the whoole level-list.
If i play fullscreen, the list still does not fit on my screen.
My screen-Size:
1366x768 pixel (biggest possible option for my device)
Maybe a button to start the editor is down there.
what can i do?
