You sir have tickled me XD
About the sprites, I am just a beginner in pixel art so adding a little 1x1 here and there tends to be an easier way of making them look nicer opposed to trying to fit the detail in 2x2.I really like what I'm seeing here, except for some of the sprites. A bunch of them have 1x1 pixels in them, and some are recolours, and the Drinium Set looks a bit 'empty', if you know what I mean. I might just be a bit too nitpicky, but that kind of things tend to bother me
I've made sure to crop the size of the image to fit the sword(no gaps).So is the sword cropped so that it fills the box within the .png file, did you adjust the offset at all within the item's .json file?
