Those reviews wailing for a hint system? They are like little babies. Push them out of your mind. I've finished this magnificent, diabolical puzzle box, and it's good BECAUSE it refuses to hold your hand. It throws you into the deep end, and you learn to swim. If you come in expecting mind-numbing relaxation, Colorcube will chew you up and spit you out. This is your brain locked in combat with a beautiful machine. You'll stumble at the start. You'll get the hang of it and breeze through levels thinking you're Einstein. Then this pretty, delicate, unassuming little thing will show its teeth. You'll hit wall after wall, leave, then have an epiphany and rush back to see your theory proven right. You'll get less than a second to celebrate your hard-won triumph before the next level loads up. The cycle will repeat... and repeat... and repeat. This game exists to frustrate you, but you'll learn to love the burn. I feel like my brain just did crossfit. I'm seeing patterns from the game in real life. I've got my friends playing too, now, and they're all as impressed and enraged as I was. This is the best, most engrossing, most rewarding puzzle game on iOS. The only thing that could improve it would be more levels – I want this game to torture my neurons until my head catches on fire. Five stars is not enough... this game deserves the moon.

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 ☺️).

Writing this on completion of the game, I have to say I enjoyed the aesthetic of the game and found it very engaging. Basing it off the primary colors of light was a nice touch, but I would have liked a color mode with true primaries and secondaries and white. Music was nice at first but quickly lost my interest. In terms of challenge, some levels were difficult and some were not. I found this distribution to be a little erratic, actually, but it's hard to tell if that reflects more on my individual approach and ability, more than the design. Maybe my biggest gripe in the challenge and puzzle design was that the number of pieces provided in the later stages often made my go-to strategy just piling on the pieces and covering the board, and while that's alright, I really missed the feel of the tighter design of the earlier levels, where pieces were more limited and I felt more of a need to place each piece in a really precise way. Probably beyond the scope of the project, but having a tool for community submission/creation of puzzles might allow for some really fantastic and challenging stuff to be made, and a little freestyle/sandbox mode could be fun and let folks blow off puzzle steam by drawing things/ creating interesting patterns with all the available tiles.
