[b]Family Mysteries: Poisonous Promises[/b] is a really well developed Hidden Object Game with an engaging story. The puzzles and hidden object scenes struck a nice balance between relaxing and challenging. Loved this one.

Family Mysteries: Poisonous Promises is an entertaining hidden-object mystery with a surprisingly engaging story. The investigation gives you a good reason to explore each location, while the puzzles and hidden-object scenes provide a nice change of pace. It's not particularly difficult, but the atmosphere and mystery kept me interested enough to see what would happen next. Enjoy :)

This is the best AM HO game so far. More variety and detail. No push key through lock to land on newspaper sequence. HOGs were varied and enjoyable. Great quality. Small Con: The big green flag on the map was a bit counter intuitive for going to available actions. This game was different. Some confusion. Sliding puzzle was quite the endeavor.

amazing game

Art is good and voice acting is alright. Story was entertaining enough though I did not alway scare for the evidence board. The game also has one major con: The fight "puzzles". They feel out of place and are confusing. (You basically have to help your opponent beat you up in order to be able to win.) Other than that the hidden objects are often hidden behind/underneath/inside other hidden objects. It felt a bit silly at times just shuffling objects around to get the one you actually needed. If you're an achievement hunter and know you cannot skip any puzzles: The very last puzzle is VERY mean compared to anything else in game. I suggest looking up a screenshot of the final result or you may spend a very long time on it. I know I did. It was painful. Worked well on Steam Deck while using touch screen controls.
Not recommended Mar 27, 2026
Randomly opened the game to find my cursor bugged. It keeps floating my cursor to the top left of the screen (no it is not my mouse or any other program on my PC). Other people have had this problem and this makes it pretty impossible to finish this point and click game.

Games like Portal 2 all share one habit: teach a single impossible trick, then spend a campaign breaking it. From rewinding objects through time to Escher geometry that loops back on itself.

Planet Coaster DLC: skip the collection, buy the packs

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
