Leaving a comment here right now so I don't forget to.
I've only just begun act 2, but so far, I'm blown away. Intelligent puzzle mechanics that aren't too complicated but feel amazing when solved (very hard to achieve but so satisfying when done right!). Something as simple as the naming scheme for files goes from a mystery to a key tool for solving.
As someone who has never played any of the games this is inspired by, this game makes me really want to try them. Cannot recommend this enough, and I cannot believe I get to play this for free.
Genuine 11/10.
