This is not the only VN I have checked out. There are others I enjoyed and fell off the wagon for period of time and return. Some VN had a lot of changes and others had some minor changes. I do recall there possible few routes on this VN and I had kept using my previous saves. I may have to scrap those saves and start fresh one.
I am really looking forward for the new public update so I can check the previous saves and then start over from beginning. Enjoy your New Years...
Have a great day and be safe...
