As someone who is generally very shit at puzzle games, I actually had a good time with this. The story and the philosophical discussions you have with "Milton" are some of the best parts of the game. I do admit I had to get help with some of the later puzzles, especially when the record feature was in play, but I genuinely had a great time with this and completed all of the endings. It's just a very addictive gameplay loop as the puzzles are not too long and the small dopamine hit you get when solving them makes it all worthwhile.
I did try out the "Road to Gehenna" DLC as well that comes packaged with the PS4 version of the game, but I was literally lost from the first puzzle already, so I think I'm just gonna skip it.
