Be aware, that to unlock this one, all the other achievements have to be unlocked in the SAME profile. Creating a new one and unlocking further achievements here won't do the job. So please don't delete your profile after completing the first run or you have to start all over again... ;-)
E.g. I had trouble unlocking the "HO scene solved in less than a minute"-achievement, even on the second run, it was the last one missing. I started a third run, tried again in the first scene - and failed. Then I remembered, that you can play HO scenes in the Extras menu and so I practised on the second HO scene like 3-4 times, until I remembered al of the locations. Then played the second scene in-game and - YES! :-D
