Blue Portals is a unique Portal mod that has players traverse through new test chambers using only the single portal device and many new test elements.
Overall it was a great and Challenging bunch of maps with a great environments, scenery, sounds, puzzles, and atmosphere. I absolutely LOVED the turrets' voices I thought it was very funny to keep reloading up the last quick save to hear each of their phrases. A few problems I had with it is that the player could get stuck in a few of the test chambers (Like place a cube through a portal and step off the button to close the orange Portal kind of thing.) I can't exactly name each one that can happen in I believe it's only one or two parts of the chambers though. One bug I found was that at the end of the 10th test chamber the final door wouldn't open for me (I had to noclip to get the other side.) All in all the mod was an excellent thing to play through and I loved it. I'd give it a 9/10. Good Luck with Future projects!
