Just wanted to update I managed to work out the solution to the puzzle I couldn't before, but entirely by accident while trying another solution and it was the least satisfying puzzle aside from the first one in the tutorial (which after doing it again is quite hard to do even when knowing as the movement has to be so specific). I've also just learned that the aiming is controlled by the mouse, but again it was by accident and should be explained in the tutorial. It's still quite hard to throw accurately and could be tweaked further.
I still think it's really promising though and hope my feedback was useful.
