In the future if you create and share a map with the PTI editor could you please upload it in the PTI section please? I've moved it for you now

I see that your workshop page says "A simple puzzle, with a cube some buttons and a big drop. Somewhere between moderate difficulty and quite hard i'd say."
The actual difficulty is EXTREMELY easy. Not much of a puzzle at all, unfortunately.
I don't know why I'm uploading this, but it might be useful to see how someone else solves your map. It can easily be beaten with 5 portals in around a minute (shown in the video).
Thanks
