I understand where you come from, but we figured it would be a bit dull for some players to have such a description, we thought trying to figure out the items would be part of the challenge.
I think what you missed on level 4 is the green bar on the top left corner. This is your stamina. You need this bar full if you want to use the blue sparkle properly. And we did such a thing because we think it would have been too OP otherwise.
