I guess this is the best puzzle platformer I've ever played. Playdead learned a lot from limbo, improved what they could, and intensified what was already good in it. Peak in atmospheric and mystery building.

I just wished this game was a bit longer, in limbo I didn't feel that it was short, but inside could use a couple extra hours of gameplay.

I don't know if I'm right, but I got some worker revolution allegory vibes with all the mass control, industrial level design and the ending sequence, and I don't care if I'm wrong, I loved that.
