Movement, combat, and the "soul" system have been fixed. No longer will you have to grind like a jackass to get the lil card thingies. The story in concept is pretty fun in all honesty- these early metriodvania's work best when there's a sense of mystery pushing you forward (ie Symphony of the night, Aria of Sorrow)- a cute lil story of jealousy and the ending is surprisingly endearing.

The dash, whip, and weapons all feel great to use. The screen is no longer absurdly zoomed in and seems to focus more on horizontal movement which is better for the Gameboy screen.
I'm actually a big fan of the cosmic, ethereal horror of this one. Feel like it makes it stick out in a great way and fits the small ass gameboy screen.

THIS MAP FUCKING BLOWS DICK AND THE TWO CASTLES ARE THE SAME THEY ARE SO FUCKING BAD
