Whenever I try to download the mod and play Minecraft, it says that it does not work for the version I have.

Could ya'll please add 1.16.5 to this?

I tried to port, but gave up early. It's impossible to port without writing everything from scratch.

Update, port to 1.16 is nearly done. I hate everybody suggesting a port XD
