Think Cube Escape but a bit harder and less creepy. The puzzles are layered, clues are not always in-your-face-obvious and even sometimes require time to sink in. The style is flat with good illustration. I didn’t use hints so I am not sure about that, but avoiding them definitely will make the game last longer. Took a few days playing on and off, and with the free price tag and very limited ads, it’s worth the play for sure! That said, to the devs… I would certainly pay to have ads removed.
