alright so unless so at least to me the sprites all appear a bit blurry, they don't have the sharp edges that you'd expect with traditional pixel art. i see you used godot which has linear filtering built in. for pixel art you want nearest if you don't want the weird bluriness to show up. you can change this in under each sprites "texture" property, or before starting a project where you don't want the bluriness you could go to the import settings and change the default filtering to nearest (it's set to linear by default, which works better for something which is high-res and has curves for example). ultimately it is a stylistic choice so it's up to you, but i find that most newer developers don't know that their art can appear crisper if they are going for that pixelated style, and it really helps to give your spritework a higher degree of professionalism if that's what you're going for. hope this cleared it up!
