If the only issue I have with your game is that I wish it was longer, then you've accomplished something incredible. Despite being a decade old, Portal 2 is still one of the best written games of all time on TOP of really fun and challenging puzzles, a great atmosphere in terms of visuals and music, and pretty fun multiplayer, even if I prefer the main campaign.

This is an absolute masterpiece and that makes it pretty disappointing that valve is creatively bankrupt and will never make another one of these games. But still, this is one of my new favorite games of all time and one of, if not, THE best puzzle game of all time.
