I both love this game and hate that I could never beat the final boss. Even after defeating the “harder” optional stuff. My Dark Souls training is punished hard by the combat system. (I love to hate it though - just so satisfying.)

Just completed this one myself - and yeah, amazing. I am sooo happy I went in not knowing anything. Figuring out what needs figuring out is half the fun.

Yes, finally. No one I know has played it, and there seems to be little interest in trying. The game consists of perfect mind-bending puzzles, with no duplicate “tricks” - just a steady growth of what is considered outside-the-box thinking.
