This was a very unnecessary action segment, and I was quite upset when I encountered it, as they said they were going to do away with these segments. Though I wasn't a fan of them, I found the action segments in episode 1 perfectly manageable, but this one was nearly impossible.
I don't know if this will help you or not, but the way I eventually got through was to just keep pushing the movement keys, even when Gwendolyn was speaking or Graham seemed to be moving on his own. That way, I stayed ahead of the ice that up until then, always got me in the third section toward the end. Also, just climb as quickly as possible, even if the action prompts aren't showing up. Sometimes, you will have to press 2 arrow keys at once, like the up key and the left arrow key if the rock you are trying to reach is to the northwest, for example. Also, try to always reach for the furthest rock away that Graham can jump to, to minimize the number of jumps you will have to make.
, and I hope you are able to make it though. In spite of this completely unnecessary segment, I thought this was the best episode yet. Which princess did you pick for Graham? Vee or Neese? I picked Neese, as Valanice had red hair like her in the original games, plus she's musical like all the Daventry family members from the original games.
