Yes, based on that game, albeit changing the gameplay, animation, boss fights and other things.
I don't have much of a plan of where to start first, and more of a spread of things that are still missing. Below I give you what it looks like so far.
Yes I have such a plan, but I will probably do it in my own version of this game than by adding a new story to this mod.
Yes and no, in stage 2 and 3 I will not change the plot too much, and more the very appearance of the characters that appear in cutscenes.
