I want to either download a mod or develop a mod which flips Minecraft 1.14.3 upside down. Problem is, I can't find one and I have no clue on how I can do it. I want a mod where it is basically just flipping the game upside down, but not the GUI's. So you now see everything upside down, have inverted controls (since looking up should make you look towards sky, but it will now be on the ground), but if you look in a chest or crafting table, its normal. Any ideas?
