difficulty spike just a little abrupt?

[Lord Victor]

for most of the levels in the first world the difficulty was a good balance although that first wooden puzzle was a little weird to solve until I figured out I just need to look at it like I would a sliding block puzzle. Then suddenly on the level "full steam ahead" I felt like the difficulty just shot up quite a bit. Particularly with the elevator part and the sliding part. I do enjoy it however. Something oddly satisfying about not being told how to avoid those heat seeking missles, not even a hint, and just figuring it out after some head bashing against the wall.
