I admit there's already weird stuff like the camera struggling with pixel resolution, maybe some animations just being bad and even when the Player is on water or singing and the Companion is only shaking because they're trying to catch up with a character on a different speed that just isn't addressed in the code.
But your stream and ArtieAllNight's show the Player vibrating really weirdly and when I try the latest exe build myself, I don't see it.
When you mention px, you mean like the actual movement or the sprites?
