you don't call it GZ Final Doom or GZ Doom 2 btw
it's GZDoom, which is opengl ZDoom, which is a sourceport for Doom-engine games
but yeah versions since like 2006/2007 have had crouch, and it has always had jump/mouselook
GZDoom has true mouselook though, due to the fact it runs on opengl and not doom's software renderer (zdoom mouselook stretches)
