Even though Superliminal certainly reminded me of the Stanley Parable and Portal, it has very own special charm, and very peculiar mechanics and puzzles that change from one level to another. In the second half, it felt more and more like Alice in Wonderland, with an endless falling down the rabbit hole and with absurd but understandable logic - and it was so admirable! I enjoyed Superliminal very much, with its clever storytelling, surprising puzzles, and with pretty strong emotions that it brought.
