This is an OK level. The trick feels like more of a "gotcha" than something fun to discover. The rest is relatively straightforward with just one small optimization section.
I was lucky to spot one fact that told me straight what side to open first and from there, route was correct and my 2 off was just an idiot thing I had done at start. Enjoyable. :)
The clutter, while ugly, hides the trick better than a clean and purposefully-designed level ever could. Of course it would be better if the clutter also had puzzle elements.
