Legend! I do need to look into de-blurring my pixel art- as I always struggle with it in 2D games. Thanks for playing though, and I appreciate the comment :D
Yes, search for a checkbox in sprite art import settings, it's often a frustrating checkbox away :P Most likely a compression setting or some kind of filtering setting.. The issue lies in the engine trying to smooth out your sprites, which might be good for high-resolution, but definitely not what you want for pixel art!
