Could you tell us what enemies or objects don’t appear so we could check on them? Also some sprites are higher res than others because they share spritesheets and making it slightly less quality doesn’t seem to affect some but definitely affect a lot more to others
Well... The bugs(the animals)on the 2nd run and gun donsent appear until you reach to the top of the tree and the balls for the 2nd run and gun on isle 2 and the cala María background there is some missing sprites, example the sea and when Cuphead take damage sometimes just stays in one sprite that's all I can say because my English is awful
