the enemies that are not from the mario world will be replaced?
Not all of them. The original idea was to change only the enemies that had an obvious counterpart in the Mario world (the original game takes inspiration from it, so that's relatively easy) and the uninspired ones.
This, as usual, has changed a bit due to the suggestions and feedback I' ve been receiving through my Youtube channel. In certain aspects, I'm afraid of disappointing the " grown up kids" who will see how some of their beloved memories have changed, but (obviously) I won't be able to make everyone happy, so I'm going ahead and if I consider it necessary I would make changes in a ver. 1.1
Just one little nitpick though: I think Kirby would benefit from being a little rounder if possible, and maybe his UFO should encroach a little less on his head so the proportions look more even. But if that's not possible due to sprite size limitations, it's not a big deal in the end.
As always, keep up the good work!
That's not a big problem in the design of Kirby's Adventure, because the perspective is lateral. In fact, I did some experiments, although I finally decided to fuse both designs because I thought the perspective gives it a nice touch.
