The following two images are an example of the art changes that are included in the volume release of Travelogue of the Succubus/Sensor. Looks like there’s quite a bit more detail, and some scenes look a lot better. Can’t comment on the dialogue since I don’t know Japanese, though I’m seeing tiny changes when skimming through. The afterword blurb has already been translated into English, but I will upload it when I eventually get around to updating all the files and compiling them into a single release file. Given the quantity of changes, this won’t be any time too soon.
