Recently saw an awsome idea for displaying lightweight "3D" graphics in pico-8 by ioil13 :D
I edited the code a little to allow for making an 8x8x8 cube where each Z layer of the cube is a different sprite essentially allowing the creation of derpy voxel art in 8x8x8 size (black pixels are transparent)
original code by ioil13 go check them out they make cool stuff :)
feel free to use or edit this code as much as you like :)
I will see if I continiue work on this depending on how much motivation I have lol.
