Inside is a work of art, pure poetry, just a perfect 10 out of 10 game. Its so good, I just had to make this blog post to share how I feel about it. I have played it through five times now and every time I play it, I discover something new about it. Its a visually rich experience, with incredible lighting, sound and atmosphere. The puzzles are just the right difficulty level and the ending is wonderfully bizarre.
Just a warning, if you start playing this game, you will not be able to stop (and nor should you).
