hmm... This is a very promising premise.
Would you consider a '<span style="color:blue">House</span> of Leaves' mode?
I really like how well the floor plan aesthetic worked for this game, so I might expand on it in the future!
I loved House of Leaves (or, more accurately, I loved The Navidson Record) so taking this in an "impossible architecture" direction is intriguing... (a friend of mine already suggested a backrooms version, lol)
I'm super keen to see what you decide to do! Still though -- it's a good little puzzle game as it is already. Just needs a little sound... and perhaps a reset button when I realise I made a mistake and have to refresh the page.
(Off topic now, but I believe I tracked down a precursor to the Navidson Record... if you have the time, I recommend checking out the graphic novel adaptation of Paul Auster's novella 'City of Glass'.)
