What constitutes life-changing and what constitutes intensive dexterity will subjectively vary by person based on their skills and tastes.

I didn't find the game to require much dexterity, but I did find it to have interest world design and ideas that have stuck with me for years.

It is not Hollow Knight, but I recall there were a few parts that required quite a bit more skilled platforming than the game theme would imply.

If nothing else, there are some sections which have somewhat tight time windows which can put a lot of tension into a puzzle game. Resetting an attempt to a failed set piece might take several minutes, adding to the frustration.
