Added the Investigation update

If you played the new update, you will have noticed a couple of things at the ending:

- The last update has been changed into "story will be concluded" instead of "story will be continued". Despite this, there will still be 2-4 updates left; wrapping up the current chapter, then an epilogue for each character, aand… that's it, for this project,

- I no longer have my Twitter, but I do have Bsky where I post about my projects - come say hi <3

The newest update adds the Investigation part, next update will add the Conclusion part. I happened to get a hold of a beta tester for this, but as it is still the start of the year and we are all still tired from all the vacationing we did around Christmas/New Year's, there is a chance some brain farts and/or typos have made their way in. If so, feel free to toss a comment in there!
