The first levels really impressed me with their ability to be designed without soft-locking yourself, however, this amazement and faith in the design caused me to get wreckless... and I did end up soft-locking myself haha. A cute and difficult puzzler either way!
As a fellow level designer, I'll ping up the soft-lock I ran into incase you want to do a diagnosis! I think my flaw playing it was that I simply "removed the obstical" that was the far left piston and upon realising I needed it to reach the exit, and then broke everything trying to reach it again. Not even sure how I would fix this without re-working the entire puzzle as the pistons that need adjustment are already used as diffrent funtions unless you add puzzle peices speific to fixing this issue, which I imagine would count as cheating by the internal design book.!
