I just updated the game page with an extra version that can be localized more easily. Depending on what you think is needed, it may not need anything more than just editing a bunch of images. Feel free to make whatever localization you want and post it where ever you need for your portfolio. Just make sure the Hololive and Nanashi Mumei credits remain intact so their copyright isn't violated and don't try to involve any money (there's a separate license needed for that which would complicate things).
If anything about the process is still too hard to figure out, feel free to ask.
