Settling cracks and spare tile
When cracks in a floor seem to run in a continuous line through a few joining tiles, it is likely because the concrete slab beneath it is cracking. There is no sure fire way to prevent this but the best is slipping a membrane between the slab and the tiles. When I see sheet vinyl already down I have opted to leave it for that reason. There are adhesives that bond to vinyl and the vinyl over a crack will absorb most movement of a slab.
More importantly, it is in the best interest of the owner to have and keep SPARE tile when a job is done! And I typically advise to replace the tiles in question just before selling the house unless you have plenty of spares, as it can occur again. It is the earth moving! At least to the new owner the floor will be in acceptable condition.
There will be more written about this later.

Cracks have appeared in our floor tile (which was installed last week). The floor is slightly soft in those parts (if you press your feet down in that area, the tile depressed noticeably). Do you think this is because the tiler used 1/4 Easyboard, or because the board was improperly installed. Does the whole thing need to be replaced?

Sorry I hadn't seen this. Hard tiles can NEVER seem slightly soft. BUT if 1/4 Easyboard was used and not fastened properly then that section could have some give. Perhaps because there is movement, SEEM soft.
That board SHOULD have been screwed AND glued down. Or so many screws used that it had NO give. And if tile is cracking it could be (in my opinion) where one board beneath the tile is loose enough to create a shearing. Not unlike settlement cracks.
As to whether your whole floor needs to be removed, certainly you need to contact your installer SOON and have both the movement AND especially the cracks be addressed. ESPECIALLY as you would want to have spare tile in the SAME dye lot to replace cracked tile, and if there should be future cracking!
