While I had fun with this game, it's not quite what I would call a classic. Keeping track of both color and angle feels like it might be a bit too much to do at at once, particularly if they wanted us to plan out chains. It's also a bit weird that one of those factors has to match, while the other has to be the opposite. I've played enough puzzle games that my instinct to match like with like kept screwing me up, even after I played a while. And games with color matching need to make sure that the colors instantly stand out against each other, while this game occasionally will do things like have two different shades of pink that you need to be careful of. Still it works despite these issues, and it's worth picking up given its low price. It's at least better than Puzznic or Panic bomber.
