Problem is, there are rooms where you HAVE to use the hint. Like 17, there is nothing at all in the room... No way of knowing anything to do. And on 14(ish?) It would not let me pick up tiles until after I used the hint.
The biggest problem is that there are just so few matches to make at all, I look across the board and on average there is at most 3 matches possible, and rarely helpful ones.
the magic is hard to get, having to clear blocks in order AND still have to clear another block to use it? The game gets way to hard once you get the 5th color...
