Hello! The game is so big that it has been separated into episodes for an easier walkthrough. When you play the episodes, you can unlock all scenes faster than you would in the "full game." For example, scenes like "Don't Break Taboos" or "Don't Be So Shy" can be accessed more quickly.
The "Completed Episodes Bundle" contains all the scenes from Episodes 1, 2, 3, and 4, excluding four premium access scenes for patrons. Additionally, you have access to multiple save slots and a skip button, which are not available in the "Online Demo Version."
The "Completed Episodes Bundle" doesn't contain Episode 5 content because it's still in early access and development. Once we finish working on Episode 5, we will add it to the "Completed Episodes Bundle."
I understand, it's possible that I made a mistake, and some phrases within the game client were unclear. However, by "full version," I meant the game with Episode 5, which is still in early access and development. Unfortunately, for now, you can only try it online.
I hope this helps!
