Okap ,I'll explain, no prob!
It's arrows to move + shift if you want to run. Z or space to interact with stuff and X to cancel or go to the menu.
In the case of the mouse I think you autorun when you move if I remember correctly, what you do is touch the place you want to go to with the left click (you can also left click to interact with stuff, the thing is that the game is better adapted to the other controls so it might, in some cases, be a bit junky or strange). With the right click you can go to the menu or cancel stuff.
And I think that's it. I might be forgeting something tho haha
Oh, the run thing, you have to start running after the chase music and the save screen.
