Thank you for the kind words, I'm very happy to read that you enjoy the story so far :).
If you've bought the game, you should have access to the Itch version, which is the most recent version that contains all the available content. New updates will get released whenever they are finished, but you don't have to pay for them again. One purchase is enough forever.
As for your questions about the images:
1) Orc pictures are usually about the character Atilla, an orc. To get to him, you have to Leave with Kate > Join the Mercenaries > Be trained by Atilla. This has most of the orc images.
2) Razaphel is on the mage route, correct. In order to get on the mage route, you have to Leave with Kate > Do not join the mercenaries > When the thief guy shows up, scream. After that, you are on the mage route.
I hope this helps :).
