bitsy unlocking doors, entering values

I used following elements to add "input interactio" / locked door opened with a code.

so i have :

1- a sprite that has a dialog and an item action.
It adds item "N" (as a number) and tells the value of item "N"

2 - 5 sprites that add or subtract "N" (and have a dialogue telling you how much is added or subtracted)

7 - locked door that checks if you have exactly specific number of item "N"
and that acts like a lock with a code.

similar approach but with letters: https://brandonmakesthings.itch.io/a-bitsy-keyboard
