1. The 'solutions' were really really really really bad. Why would you need to use an item on an object you already interacted with?? (I'm talking about the letter box next to the couch.) Oh yeah, let's just throw a lit match ON A CARPET JUST TO FIND A SCRABBLE PIECE. The clock puzzle was REALLY bad. Wait, actually, just go through all of your solutions, one by one, and ask yourself for each one, "does this make sense?"
2. The locations of items are horrid. This game literally tells you to tap everywhere, and if you want to win in a respectable amount of time, you NEED to do that from start to finish.
3. The 'clues' are abominations. I'm too lazy to write anything else, but just look at your clues one by one, and ask "do these make sense?"
