Fun & challenging!
This is an excellent game, full of challenging puzzles. It will keep you busy hour after hour. The multi colored option adds a fun, slight additional level of difficulty. I would like to see a way to earn / purchase a hint. Otherwise, you can work on a puzzle for some time,not knowing the answer to just one or two words. You then have to surrender without ever seeing the location/ solution! Additionally, it would be helpful to see the puzzle solve itself, when we run out of time. Lastly, have you considered adding number only puzzles? Thanks for a great puzzle game!
