Played this for 2 days (not being able to save was a small frustration, but I found a bug(?) where you can tab out of the game and then restart with your progress intact after the opening scene, which helped).
The writing is top-notch and the puzzles are engaging. I like the method of slowly uncovering clues making the game a lot more interesting and fun to play than the standard visual novel where the only player input is a dialogue choice here and there.
I think the only thing bringing this down are the bugs. Namely, if you click a note on the dresser on the left, it seems to disable any more clicks in the game (at which tab to quit and restart becomes pretty useful) and at one point the options menu in the journal became inaccessible for some reason.
Other than those issues, it was a solid experience and I was super glad to play it.
