Hey dude,
I love Portal and want to collect some gameplays (first blind runs; always aren't the fastest and intended solutions, because I take any time to look at the map and its possibilities), speedruns and bug reports.
My records should help you to understand how the player thinks.
Well, I hope I can support you with my uploads to fix any bugs and make new awesome maps.
Here are yours!

If you like it and/or it helps: *THUMBS UP* 
opinion & comments: little too, but much better
I think it's illogical to stand in the air without any platforms or ledges.
"medium difficulty"? sorry, as a friend, that's a hyperbol 
THX for mapping...
Keep it up!
Haha, sneaky... I'm glad you're able to solve it. 
Anyway, thanks for the video and feedback! Very helpful! Thumbs up!
