It should appear in front of you after a grab-release I think, you don't have to hold it. I just tried it and there seems to be a bug if you hold it and drag it. Both the hand and the backpack disappear and you have to grab-release again several times for it to appear. Thanks for letting me know!
It worked , the way you told me to do .
I think I was used to do like in some other game where we have to hold it in front of you . Then in the game I'd make disappear it each time before you give me the tips to just grab-release and then I can see the backpack .
Thanks you soo much for you fast answer . Love your game both of us (Aki bonbon and tomboy adventure , I hope tomboy adventure 2 gonna have a quest standalone version.
Thanks you again keep doing greet jobs and take care.
