Thanks ! Indeed, I need to make the pieces more visible. Some people get the same problem. There is flowers in the bag, the chest have to be open with the key on the floor, and the book wich is reverse (? sorry for my english between the mangas. I wanted to make the pieces visible by their contraste with their environment. The book is the only one wich is reverse, the flowers (pink wrap) are visible from the bag (blue), etc. You're right for the arrows and the inventory system. Next time it will be better, I promise !
