Ehi sorry to get back to it only now! No at first I didn't get how to properly switch from ceiling/floor but then I got the hang of it. The only technical issue I got was from the sound but maybe is some compression for the web version? I finished it and got the cool ending with the awesome cutscene, so cool.
I got the hang of it when I stumbled fighting against the rotating blade,that section was hard and I tried going fast in and I saw that if you keep switching up and down you can use the power like some gravity suit and dodge the enemies.
