Well,
I must tell you, I hope you understand: I was interesed by the text and ideas, but I can't really give you a good score.
But, I didn't wanted to just do that. So I'm leaving a comment, (an useful one i hope) to compensate, maybe.
I really like when games open doors that are usually ignored or taken lightly. Happines is a very heavy topic actually and you have several ideas, some of them I concurr, others not so much. In any way, I must confess I was a little disapointed by the game itself. I understand the limits you got, and I celebrate your attempt to cover the topic in this challenge.
I think you weren't able to carry the ideas presented in text to the game... I guess you noticed that too, so I propose to you a challenge/technique, next game write these ideas, these text down... but do not put them in the game, and try to translate them into gameplay alone. I do not have a problem with text, but ¿What if the ability to write down the concept free us from the obligation to gamefy it? You know, limits (self-limits too) are great for learning new things, new ways... Maybe you are used to write more than design games... (maybe, i cant really know) so, if this is the case, you could force yourself to not write at all (only because you can write)...
Well that is a proposition you can dismiss, of course, I hope you understand my real message: I look forward to your next game, and i know it will be better.
PD: sorry for my bad grammar, i hope the comment is still readable
