Thank you so much for your understanding and the screenshots! They were very helpful. It looks like you have the most current version to me. Are there certain parts are you having an issue with? If it's only CG illustrations for Ch 05-07 that you are missing, they haven't been released yet.
Because of budget issues and having to change artists, I decided to finish Book 01 without them. However I have been working on them. They'll be released very soon, however, in an update. When the game is updated, you should receive an email from Itch.io.
Oh but if you aren't getting ANY CG illustrations, like not even Four's sniper scene, then please let me know. I will double check the upload when I get to my desktop tomorrow.
