Open-ended discussion on creation and design

Agree with that layout plan, but make sure the extra journeying through previous areas is varied enough to justify it - it shouldn't feel like backtracking.

Also, in my opinion if you are planning on having a puzzle blocking the players progress, make sure it is either easy or well explained, or more preferably both. If it is complicated and not well explained, and if it cannot be avoided, then you risk losing some players.
