On the complaints about Armature, Bloodstained is going to be a much easier game to port then their previous titles were. All their other ports were of big budget retail games that were all 3D, which offered a lot more problems. Bloodstained on the other hand is a 2D game being made on a low budget by IGA, so you know it's not exactly going to be pushing the PS4/One hardware, making the porting much easier as well.
So yeah, porting this game isn't exactly going to be rocket science. If Armature can't handle this then they might as well just leave the industry and go back to school for something else because they clearly fail at their choosen profession.
