From there, we designed our new levels based on what made the best levels of the original version good, discarding elements that annoyed or frustrated the player.
From the start, the PSP version has been built on the premise that the original game was the best revision of the game and that it wasn't broken - so why tinker with a winning gameplay formula? For the new levels, we analysed what were the best levels in the original game, what were the worst and what were good to play or just long winded. We haven't done anything with the new levels to fundamentally change the way the game works, but there are fresh gameplay elements in our level designs that weren't used in the original. In total there's 156 levels for the player to get their head around. Yes, it's a mixture of original and brand new levels.
