Which is a bit of a shame. The add-on pack is slightly shorter but of a much higher quality than the original! So for half the cost, you get a few more levels that are much more clever and visually interesting.

Frankly, if they released another pack at full price, I'd be thrilled. Forgotten Shores started with the same slow pace, but by the end the levels were truly lovely works of Escher art. The final level harkened right to some brilliant bits in Fez, which is a far larger and complex game.
