I added some extra platforms to help with some of the most difficult parts of the wall jumping - I've recieved plenty of feedback though that in general there is too much jumping/wall jumping in level 3. I definitely don't plan to use nearly as much in future levels.
Level 3 is also probably the upper end of what I'd make in terms of map size/complexity in the future - most levels will be easier to navigate, similar to the previous levels. There will also be some kind of actual map in game in the future, though they can be a bit complex to set up - I still need to decide on a method to use for it.
