I know peeps might have said "Will you be doing the rest of the game?" Which... Mmm, when it comes to copyright shenanigans, I can definitely understand why you couldn't. Plus it'd probably be quite the task to throw in Cathedral Ward, Old Yharnam, Yahar'gul and all those other places.
Honestly, I really like this game as it is -- IMO, it's more than just a demake; it's like the DLC we never got. However, if there is one thing I would like to see added?
Saving Gilbert.
I'm a sucker for tragic stories. And I really, REALLY love the plot twist in the game. But one thing that's always left my heart broken is not being able to save the poor guy - it's especially worse after hearing his deleted dialogue from the OG game where that could have been an option. Considering how the demake took a bit of liberties in differentiating itself from the OG, that could work as a sort of third ending? The gates to Cathedral Ward are now open; but before the Hunter departs, they return to that window one last time and leave Gilbert with Iosefka's blood vial.
If ever you decided to add more to this game, I would love to see that.
