Meh its ok...
I have mixed feelings with this one. On the one hand its a pretty great idea for a puzzle game. On the other hand, it was a bit too easy. I read a bunch of the other reviews and I see other people had a lot of trouble around puzzle 16 or so, but for someone like me who grew up playing Lolo and other legendary puzzle games, this wasn't so hard.
The way to beat it is simple: make each move where you dont cut off two like-colored blocks. If you cant make a move without cutting blocks off from one another then hit undo or clear and start again. There are in the end only so many moves you can make; its just a matter of having the patience to find the right ones.
The puzzles I seemed to have the most trouble with were the ones that had none of the black squares in them. Those black squares made the whole process of trial and error a lot quicker since they almost immediately limited the number of moves you could make without cutting two like-colored blocks off. The puzzles where there were no obstacles and thus the number of opening moves was greater were the most difficult to solve. Overall, though, not a bad hours worth of fun.
