.. and what the heck. I thought the game was weird until the very ending and then it suddenly explodes into weirdness that only a Japanese game studio could possibly one up.

I desperately wanted to know more about the mythology. The world, what was going on etc. But obviously nothing was explained. I've googled some and read some interesting stuff, but has anyone else found nice articles with theories about the game?

I cant decide if I love the game or if I am very afraid of it, one of my weirdest experience (game or not) in my entire life. 

I had my own theories that I felt were just as good as anything I read online.

As a game, it wasn't very challenging and really a step down from Limbo but it really made me think when I finished it. That's a good thing.

Really, I don't think there is a single mythology. It's up to you to interpret it as you see fit. But then, I'm just some guy.

While I fairly enjoyed it, overall, given how much I love Limbo and how long it took them to make Inside, I was somewhat disappointed in the end.
