[PTI] Circular Logic
A bit of logical thinking, but not that you'll be going around in circles. Maybe a couple of times. It's not a long map, but it should be between easy to medium difficulty. Just something I tossed together one evening.
Fixed a part where the player could get stuck. Thanks AlfredoVictanir for pointing that out.
Really cool map! It had me running in circles for 20 minutes before I snapped something clicked. Then another 10 minutes to finish. Probably just tired.
20 minutes? I never intended to have anyone go in circles that long. LOL. You're probably right, just one of those days. I get those too. I realize my brain needs defragging and sleep on it instead. As for the spot you mentioned, I went back and tested it. You would be correct about that. Portalling into that situation is of course not part of the intended solution, but the player could inadvertently do so. I will perhaps edit the map and remove that cubic section below it and extend the gated panel downwards. This way the player can just drop down. Thanks for pointing that out.
Great little creative chamber. Fun and enjoyable!
Here's my blindrun:

5/5. Excellent.
Thanks for mapping! 
Cheers! 
Glad you liked it. Thanks for sharing your video.
The intent was to portal above it, then fall into the beam, then re-portal so that the beam is directed to the button, then take the cube and reach up with it and place it into the beam just above you going to the button. This being done while the beam keeps you pressed up against the grated barrier.
