I played a very large chunk and was enjoying it, but fell off when I kept dying while trying to discover more big pieces of the puzzle and had to repeatedly restart, especially for things that took a bit of game time in the loop to reveal themselves. It got tedious and frustrating.
I still would like to see the ending myself which is why I haven't sought it out yet, but having to jump back in and reacclimate myself with everything is daunting.
