Greak Memories of Azur - Playthrough Part 2

After a boss battle Greak was finally reunited with his sister Adara. She fights using projectiles and can briefly fly, allowing you to traverse some bigger gaps. I also noticed that she can hold her breath longer under water, but it too big to fit through small holes. These differences really make you feel that the characters are different and not interchangeable. I also found out that you can pretty much abandon one character in a level and go back as far as you can including teleporting to Azur. Then I was a bit confused of where to go next and the issue was that I didn't have enough inventory space for a couple of quest items. At least both Greak and Adara have separate inventories, so this gives you a bit more capacity, but it is a problem that shouldn't have been there in the first place.
