there is no bunny hopping in blockland
there is the ramp momentum glitch but this is very dissimilar to bunny hopping and can only go in the direction of the ramp slope ie: why you cant strafe and turn because it is infact not bunny hopping, bunny hopping has to do with building up momentum in the air ramp hopping is actually something like building up momentum on the ground and then holding that momentum when going into the air
removing ramp jumping is really easy, simply adding a small delay to subsequent player jumps will prevent them from doing the small ramp like jumps while not affecting their normal jumps
(it's a variable on the player datablock called jump delay)
