We've defintely been tricked with Halloween: Trick Or Treat. Read the details before you download and you'll be told that it's an all-action game in which you collect treats as you 'explore' the haunted house of a nutty professor and bump into friendly ghosts, witches, bats and the like.
What we're not being told is that this is a hidden object game. That means you're presented with a scene in a haunted house, given a list of items to find and then you have to tap them with the stylus when you see them. Some items aren't even Halloween related - you'll be searching for a sombrero in one. Awful.
