Wow, that is honestly awesome! As I suspected, the areas are significant aspects to his character, I was at least correct with my thoughts on the Garden haha; but everything else is very enlightening, and I'm glad to know that there is so much thought put into this that I am finding myself quite ignorant! You have, perhaps inadvertently, convinced me to play through the game again hahaha - I love this game and the symbolism it provides, I will definitely play through it again and probably obsess over details again. Thank you for the response, you did fantastic!
Oh i forgot to mention, if you are only wanting to play mikails story i reccommend giving his friendship routes a chance as well. I strongly believe that friendships can be just as deep as romantic bonds and I tried very much to make all 6 possible endings with each companion unique, satisifying and reveal different aspects of their character. I made sure to enable the skip function everywhere i could XD.
