I really like the vibe of this, there are some fun things in here! Though in my opinion, the MNES should really be an alternate Virtual Boy XD, here is my feedback!
+ Clear and readable layout
+ Lookback adjacent information being colour coded in location keys is a great shorthand.
+ I love the random table and that it has a mechanical impact
- Location keys are a bit dense, they could do with a bit of simplification and editing to make them easier to parse at a glance.`
- A bit unclear if the players can refuse Lookback, I assume they can, but the text implies they are just administered it.
- No guidance on creating the PC's original personas, even though it is important to the module, even a mention of doing this beforehand would be helpful to wardens.
- No good reason to take Lookback, it would be cool if it provided a mechanical benefit (stress relief, or advantage on a check/save perhaps?) or there was a mystery/clue/puzzle that required its use.
