Hey, thank you for your detailed review!
- You can open the gallery to see if you have any pics not yet unlocked. Though the game doesn't show any notification if all the pics have been unlocked, I will consider adding such thing.
- Interesting observation, I will check it
- Yeah the catalog still needs to get updated with more categories and words; Also a category won't show up anymore if it doesn't have any words left. I think I'll change this behaviour to stop showing when it reaches like 50% of the words
