The demo version says you throw the stone with R but it goes to the menu. The inventory says to use the space bar and he jumps. On the controls there is no letter for throwing...

I am noticing that it is not "just" throwing rocks it is anything to do with a touchpad... I am unable to move max (me) the way I can if I have an external mouse it is if the touchpad does not have a high enough priority to process what is needed to "look" while running which may be an issue by itself, but with an external mouse I can move directions by looking in the new direction.

Hi Leonardo. At this point, you will have to connect an external mouse in order to throw stones. This is however something we will look into improving in the future. Thanks a lot for your feedback:)
