I can't help much on this but i'll try to answer
No, you don't need the Donkey Kong Soundtrack
I know, most of these issues are recurring but can't help much, the visual glitches like the villagers with screwed up sprites, some are brighty and has white outlines and lot more is becasue of the engine updates altering a lot of the code that was intended for an older version, also the fact that i lost the original files of each sprite so it is not possible to come up with a fix :/

Pretty much sorry for the dissapointment i give to ya

It also completely screws up the sprites of the villagers by the campfire, they glitch and flicker off and on, sometimes changing skin.

Ok after using this it looks pretty good but there are issues with a few of the sprites. They have bright, white outlines that make it very ugly to look at.

it looks a lot like Sphax but I dunno, does it really need the donkey kong soundtrack though because I really do not want that in my game
DK is great and all but I want the OST for Delver playing.

i'm... decently sure this is the Sphax texture pack...

Kind of reminds me of Spooky's house of jumpscares

wait so when delver first launched this is what it looked like? interesting change in artstyle

YES good job

awesome

I found it on Discord, and I was a huge fan from beginning, thumbs up
