UPDATE: Bridge Constructor Portal 4.0! + Level Editor via Steam Workshop!

Dear test subjects,
we are happy to announce the brand new Level Editor as part of our latest Bridge Constructor Portal update:
Create absurd test chambers, publish them in Steam Workshop and play levels from wannabe engineers from all over the world!
Please note that a few physics bug fixes and tweaks were necessary. The fixes affect some of the test chambers you already built: The anchor points in levels 35, 38, 42, 44, 51 had to be shifted slightly and thus require minimal adaptations of your constructions, Perhaps, though not necessarily, other test chambers might as well need small changes, depending on your solutions. We are sorry for the inconveniences.
We hope you will enjoy the update and are looking forward to see great content from the community!
Known issue: when you download a level from the Workshop the play button is sometimes missing. Simply restart the game in that case and you are ready to go! We will fix this issue as soon as possible.
