Hi Silvia! Thank you for the review! Level 8 is definitely my favorite as well, Urodela did a really good job on it :).
When you say the ghost moves through objects, you mean he moves through the objects he can merge into correct? If so, we previously had collisions on those objects but they got annoying sometimes so we change their collision layer. I definitely would like to know if others thought that this would be better to bring back! Thank you for your insight on :)
