i played this once when it was released and iirc i got too scared and had to stop after a few minutes but i just played it again and like capt haistings i also thought it was one of the most interesting game experiences i've ever had
the depth and intricacy of the references to increpare's game is really cool and feels like a very loving/respectful tribute, i also love the way its sequenced together, feels very like 'natural' + 'fluid' movement between interactive and non-interactive segments, and between cgi and live action. the different visual techniques are cool, 'striking' but 'restrained'. especially love the inset videogame frame against the video background like you can see in the third screenshot on this page
wish i had played the whole thing earlier, but happy i found it again now.
