That seems mostly right, except for a couple
To me it's seems to read
Top Row: Magic Box on side, Open, [Unknown Symbol], Large Middle Symbol, Feed, Points, Gather
Bottom Row: At Same Time? Or [Unknown Symbol], [Unknown Symbol], Gap, Weapon, Magic Box on side
The Large Middle Symbol seems to be 2 magic box symbols, with the bottom one flipped upside down. Both are mirrored.
It seems to be that it's all one statement, and that in the Apoticon language the sentence is started and ended with the symbol for the subject. (The magic box in this case.) Trying to make sense of it, it seems to mean: open [unknown] feed points gathered [unknown] [unknown] weapon. This seems to be instructions for using the box, so perhaps we can use our knowledge to fill in the gaps left by the unknown symbols. If I was a betting man, it's say that one of the bottom left. symbols means "Random"
