I'm a bit late, but I just finished Portal

This is the best puzzle game I ever played. I don't know why, but it just felt perfect. how the game progressively turned from a safe place to a weird, creepy and dangerous place, how it make me feel bad and satisfied at the same time by my actions...

This is the first place I felt something was really wrong It was like if I wasn't the first one to be there. Then, when the voice told me that other people heard the cube say things, I tried to hear stuff, but nothing happened. The final boss was something hard too. When the orange eyed ball screamed I felt so bad... But I knew it was a part of the voice machine.

Also, in the credits, I noticed that Gabe Newell's name was not first, it was somewhere between all the other names. It's really some quite humble action, in my opinion.

Anyway, I'm still feeling weird from the ending, I don't really understand what was the voice. I could look for it but I intend to buy portal 2 when it's on sale, and I think it'll answer most of my questions.

Just wanted to share this, it's an amazing game
