wasd - lateral movement eq - vertical movement arrow keys - to look around kinda laggy but added chunks to improve speed added depth sorting but it kinda sucks for larger objects (common problem with painters' algorithm) - uses Insertion sort which is probably the best sorting algorithm for 3D projects
Azex tri filler from https://scratch.mit.edu/projects/885002848/ I think I used a tutorial by @TheGreenFlash for sprite 3D which I later converted to pen Insertion sort is also made by @TheGreenFlash I think
