Let me start off by saying that this game is exactly what it appears to be. A challenging, entertaining, incredibly satisfying puzzle game, that takes a fair bit of time to get used to. Up until level 20 or so, anyone can solve the puzzles by just moving the pieces around. But after that, you'll have to gain a better knowledge of exactly what you're doing. You'll have to actually understand the meanings of the colors, and what happens when they overlap. I just beat the game, and have to say that it's one of the best puzzle games I've ever played. It's incredibly well made, the soundtrack is super smooth, and the puzzles are just hard enough to make you take a step back and think about things, but not impossible enough to make you abandon the game. Like I said, I just made it through, and I can tell you that hints would ruin the gameplay. The struggle of sitting back, thinking about a puzzle for a day or two, and the satisfaction of figuring it out is what makes this game so great. This is puzzle purity at its finest, and I highly recommend it to anyone who calls themselves a puzzle-gamer. Or anyone who likes primary colors and/or hexagons (Like myself ☺️).
