I’m really enjoying working my way through these on my iPad. I have to look up a clue about once every “episode” usually right near the end and every time so far it’s because I’ve missed something obvious. Something I enjoy about these is that there are achievements for each room, so I’m looking forward to replaying to try and get the ones I’ve missed. They’re getting progressively more challenging and sometimes the clues built into the app aren’t related to what I’m struggling with at all, so I recommend using the walkthrough on the wiki if the clue on the app doesn’t help.
