Use keys W, A, S, D, R, F, Z, X, and the arrow keys. WASD+RF: movement arrow keys+ZX: rotation WARNING:The filler got laggy when the camZ was very big! So far, I've taken out the filler. The sorting will take a while, since I need a fast but simple algorithm.
With a HUGE thanks to @WO997 for giving me the idea to do this. I will be updating this for a few times over some days. v0.4 - SORTING v0.3 - converted the drawing to list-draw. this will be useful for sorting the items v0.2 - added shadow, edited tri-filler v0.1 - release(need sorting, more shapes and a better tri-filler)
