I just checked out your video- Well-spoken, and you really touch on some good points! I had the same thought about "fun" being a metric for games, and I think it would fit better if the term "engagement" or "immersion" was used. Cause really, if we're looking at traditional "fun" games, then to say something is "really fun" ultimately just means you want to keep playing it or experiencing it, for whatever reason.
Anyway, I'm super happy my game resonated with you, and honestly, I think you summarized some of those sections better than I could've. I'm also glad you left out most of the content- It really is designed to be experienced first hand.
Thank you for playing it, and thank you for the kind words!
