In Tangle Tower you play Detective Grimoire and his assistant Sally as they investigate the murder of Freya Fellow. Tangle Tower is a manor with two towers, all sitting on a volcanic lake. Two families, the Fellows and Pointers, live there and each of the ten characters has their stories and secrets.

Each area is a static picture. Tap on objects to examine with Grimoire and Sally providing comments, and they do talk a huge amount throughout the adventure. Some objects become clues which you use to answer questions (there is a clue page so you don't have to remember things and even things that you'd think would be clues you probably don't have to remember). Other objects are puzzles that if you solve reveal a clue or open an area.

Then there are the inhabitants. Interview each one and get their statements. Ask them about each of the other suspects. Ask them about each clue you find. Each suspect has their own story and distinctive talking style (the voice acting is top notch). Once you ask the right things a suspect gets tagged. Then you talk to that suspect and figure out their secret, most of which of course have little to do with the murder.

It's not a hard game. When you get a puzzle wrong Sally provides a clue then more clues to help you solve it. If you get stuck there is a help button that tells you a next step (go to this room to find a clue). The ending is a bit long and scripted as the bad guy reveals the history of the tower and why they murdered Freya.

Like many mystery stories I'm not sure if there is enough information to finger the killer before the reveal scene. But it's an engrossing story and there are so many little plots going on. It's on the order of a 10 to 20 hour game and fun throughout, mostly because even if you don't seem to be progressing Grimoire and Sally have great banter.

Overall one of the great Apple Arcade games.
