It starts off just right, with pleasantly fun surprises, then the puzzles get too hard but there's an easy happy ending, and you can make levels that let you play however you want to play instead with the level editor so it's okay that some of the puzzles are sadistically torturous. There's a little something for everyone in this game, unless you want a real-time game instead of a turn-based game - then you're just out of luck, I guess.

ROSE IS RED
TREE IS WOOD
HEAD IS HURT
GAME IS GOOD

Gets really difficult really quickly, but I knew that when I bought the game. If you like truly tricky puzzles, you'll love this game.
