The coding is super cool. Check it out right here ^ I tried to fix the empty space. it either looks horrible or would require another 4 sprites and a little bit of code tweaking to go with it which would mean more loading time and more strain on computers. Also, I know about the visible glitch on the right. I don't care. If you want to fix it yourself or tweak the code, just remix it lol. works better with slower movements.
