Thanks for pointing that out. I've moved the turrets closer to fix the exploit. It should stop that from happening.

I can see what the player is supposed to do in here but it's easier to place a portal in the far left or right above either turret, jump through, then jump to the exit door platform and leave, everything else is optional. Players will always seek to find the easiest way out a chamber, you might want to fix this little exploit so that your intended solution is the only solution.

I've got a little collection of chambers going and I'm always interested in feedback on each chamber or the collection as a whole. I'd be grateful if you'd have a look:
