The concept was a lot of fun, and I was genuinely excited to spend the time figuring this out. I think I got the first few buttons relatively quick, but spent a lot of time on the final one, and well...

SPOILERS BELOW::

So apparently, you just have to press the first two buttons, then leave. The third is never pressed.

I recognize the game never said you needed to press it, and the only trigger for the final button is to check if both of the other buttons are pressed (plus a commented laugh) but I can't figure out if this is genuinely just a troll and the way to beat the game, or if I missed something? There are so many unused elements, like the radio, or the bookshelf. Was all of that just a misdirect and the point was to make you run in circles until you eventually try the door?

Developer's here. Thank you very much for playing and reviewing our game. It was a big surprise to see notification about this game as it was a long time ago.  It was a great gamejam experience developing this game. Some game design decisions were made due to limited development time. Though it was the big idea to make a lot of distractions and an easy solution which can be performed Just In Time after some attempts. Book shelf and radio were meant to be useless and just waste your time :)
