Clean Slate

The reason why I gave it the thumbs down is to warn you it's not for the casual gamer/puzzle solver/visual novel reader. The "hints" to the puzzles only offer one or two basic hints, with no option to skip and no ability to choose your puzzle skill level. When the developer says "science-themed puzzles" they aren't kidding. The toughest one has to do with the genetics of eye colour, where you have to determine the parents' eye colours based upon the eye colours of their offspring. Another puzzle is involving the periodic table of elements, and you're supposed to determine four unknown elements by just two of their properties. Besides the lack of hints and inability to skip, you can't print out the instructions for the puzzles which gives you a primer, which would especially help with the eye puzzle. You can choose do do one of the easier puzzles initially, but you still have to solve one of the most difficult puzzles after. There are no guides or walkthroughs available, and the developer doesn't show any interest in producing one...many games on the market have guides built-in...not this one! So if you're up on your science and love solving puzzles with no help this is for you. But if you're an average gamer avoid this one, which is disappointing as I was getting into the story...but will be abandoning it. If I could still get a refund I would!
