This could have easily just been another set of puzzles in the same formula as the last game and I would've still enjoyed it, but this game pulls no punches. This one definitely can't be beaten in one sitting like the last one. It very much starts at the level of difficulty of the last game and continues from there, resulting in some pretty grueling puzzles in terms of length and detail. Like the beginning of the game says, no guessing will ever be required, but in order to get through the game without guessing, a hell of a lot of attention to detail is needed. Like Picross, it's about spotting the one place where a cell can go, but the added mechanics and size of many of the puzzles can make that process take quite a while. Minutes will be spent combing through every hex looking for the one possible area you can solve. Add to that the fact that getting 100% requires beating levels with no mistakes, and some of these puzzles had me tearing my hair out. Maybe a little rougher than the last game, but still a good time as someone who really liked the first Hexcells.
