Game fits into the overall storyline quite nicely, although the ending threw me off a little. SPOILERS AHEAD
When you leave, the apreature walls seem to have been standing sturdy for quite a while, but in portal 2, they are not there, just fields of wheat. It's kinda strange thet over the time chell was testing, a whole field of wheat grew, and the walls collapsed. Perhaps the fall with potato glados was everlasting eh?
Also the puzzles were amazing.

This game is so beautiful bro

i like this portal game, because it has an advanced technological concept in the retro era
