There was a lot of levels where you only needed 2/3 pieces to win, which I'm not sure was intended or not. The character could definitely move a little faster, and giving each tile a slightly different hue could make it easier to know which tile is where when they are grouped together.
That said, it was entertaining enough to play all the way through, and I was surprised at the amount of levels, and if you continue to work on it, there's plenty of expansion potential (tiles you can only walk on once, multiple people and flowers, dogs that chase you, etc.)
