Your game is still a mish-mash of old-school dungeon crawlers in terms of graphics. Changing a few pixels here and there does not mean you can claim it's not "stolen" anymore. I can clearly still recognize assets from other games, from the items of Eye of the Beholder ( ex.: potions, colors slightly changed but otherwise pixel identical ), to the magical runes at the right on your screenshots ( clearly stolen from Ultima Underworld, proof:

The forest tile assets are still Eye of the Beholder's. Changing some pixels and colors makes it a derivative work, but that still can't be considered an original work and you'll still be in trouble if the copyright owners come knocking on your door.
What I don't understand is, since you went over the process of getting an artist to remake the assets, why did you remake them near-identical to EOB ? Why not just go for a completely different style ( not just changing some colors ) that's clearly different ? Tons of games are doing that just fine. Look at Grimoire.
