I have a few.

1. What's the key to perfect level design?

2. What's the secret to Ori and the Blind Forest's level design? In detail, what key things were you and your team aiming towards and what processes did you embark on to achieve them?

3. What's your favorite example of level design in any game and why? Also, on the flipside, what's your least favorite example, and why?

Thanks.
