I also just got it for Switch, and I love it. I agree that it's surprisingly challenging. I've been playing through Crash 1, and there are a few brutally tough levels. I read that they made them more difficult than the original due to the physics, and I can see that, as I don't remember it being that tough.
Have you done Stormy Ascent yet? I decided to try it last night and holy shit
I started with like 60 lives and had 5 left at the end. I was just glad I made it
