Played it just a few weeks ago myself. Totally fun game.
We do game nights every couple of weeks when we aren't in crunch mode and we talk about the fun, overall flow of games, and what we like / didn't like about it.
How do you make it better, stuff like that.
Inside was really fun, plus we played it old school - no cheating on the internet. If a puzzle took too long to decipher, we shut it down, then picked it up later.
But I did use the internet to watch the alternate ending.
Only complaint was that I'd like more puzzles.
