The movement and controls for the game were very smooth. I enjoyed them.
I really also liked the idea of the slowly approaching boat. It was another way of showing a time-limit to the player without it being another UI element. It was a shame that the only time you could see the boat approaching was when you were at the beginning of the game and at the top of the hill. Perhaps having other, smaller vantage points would provide the player with more ways of showing their time limit without having to resort to a number on the player's screen. Regardless, it was still an enjoyable little game.
