Thanks for the feedback. For future reference, pressing TAB brings up a notepad for the purpose of taking notes.
In the future I will try to visually tutorialize this feature better.
a suggestion: separating the tab button indicator from the organizer text might help communicate this better to players. in the tutorial level, you can temporarily indicate that tab brings up/lowers the organizer. once the player uses it for the first time, you can have it go away. similar suggestion for the rest of the controls--at the very least, indicating the menu button, given it has instructions for all of the controls
