I figured out the "turning the light off" mechanic, and a "ride the box" technique, but I feel like there's other major mechanics/techniques that I haven't found yet! Any help, please? 

Level 3 (Snow): I have 6/7, but can't get
- The Wall

Level 4 (Catching): I have 4/7. I solved Trapped, Stay, Position, and Gap, but can't get:
- Offset
- Crossing
- Setup

Level 5 (Corners): I have 3/3! 

Level 6 (Layers): I have 6/7. I got Across, Flight, Fragile, Canyon, Escape, and Slot, but can't get:
- Transfer

I gave up at Level 7 (Variety). 

Fantastic game! I'm looking forward to enjoying the solutions once I get unstuck and make progress, and seeing the rest of the game.
