Thanks for your feedback ! Controls should be more present in the tutorial, that's noted. For the 6th level, it's intentional and tbh not very explicit (there is a platform on the left that falls if it feels the weight of two players, with that, you'll be able to go on the platforms underneath). We put a wall on the right so that you're forced to take the long path underneath (the invisible wall on the right disappears when you start to be underneath).
