As one of my friends excellently put it when I found out about this game, it's a "blursed port". It runs well on my 48K but I had to adjust my monitor to see the blue terrain properly on the black background.
Thank you for the feedback, I must say that I didn't think that it could happen. I'm sorry but I the only solution is change the color of the background or the terrain, but the game may will lost the soul of Hollow Knight.
