Is it much of a actual puzzle-platformer? Or just "reach this switch to continue" puzzles?
I'm not real far but as I kind of alluded to, sometimes it may take you a few minutes to even figure out what a switch did. Did it remove an obstacle, cause a cube to become an elevator? You still have to continue upwards to see. The orange blocks appear to be the ones affected by the switches.
I've found times where I've gone the wrong direction and had to backtrack to figure out the right way. And with physics involved, you still have the platforming aspect too in which you may miss a jump and have to start again from a checkpoint.
There's then red blocks which will kill you and you often have to time your jumps based on the movement of one or more red blocks.
I guess the best way to describe it is a vertical 3D maze with platforming elements and some puzzles. Technically you are right in that the switches do allow you to continue. I don't know if that will always be the case later in the game or if more elements are introduced.
I'm enjoying it. But I also like ball rollers and platformers and am not always wanting something that's incredibly difficult but still takes some thinking.
Edit: Well, now I'm 99% sure that there is more than one way to reach the top. A new anti-gravity twist is making it a lot more interesting to try to figure out how to keep going and taking me on different paths.
