Alright for a quick time-killing session.
Not that anyone's reviewed this in a while, but might as well put my thoughts down.
Nice gimmick, I don't mind the sounds. The change-up to the Match Three formula I believe is done to give the player a sense of more control over what's happening in the game world, so that there isn't that situation where you game over simply because there are no available matches on-screen. However, I played this game a few times just to get a sense of it and I must say that even when I was trying to create color chains I didn't need just to refresh the screen, far too often I would have a cluster of primary color crystals that floated off into the corner by themselves and I had no way to get back at them because their proximity from the rest of the floating crystals put them too far away for the radial selection to register an attempt at a connection. It wasn't anything that I couldn't work around, but if the gimmick of the game is to keep this feeling from happening like in Match Three, where a whole quadrant of the board could be off-limits because nothing's setting up to match, this game doesn't completely alleviate that issue but simply dresses it up in a new gimmick.
It also would have been nice to directly select the combined orange/green/purple crystals, but I can see why that wasn't allowed.
