Wow, this one is a great game! It's a short experience, but it's perfect for what it is! The controls are good, it plays just like any other puzzle escape-room horror game. The only complaint I have is an indicator of where you can click would be vital: I initially got stuck because I didn't know what and what I couldn't click, so I just clicked randomly. Maybe an "E" on the center of the screen while you are looking at something that can be interacted with would fix this problem, and also teach the player what they should click to interact (I guess it's not obvious for everyone).
The ambience is perfectly creepy, the voicover is great, and the story is...unexpected to say the least, but appreciated. One thing is maybe the clash in artstyles from this game and other external references (while watching the video for the first time I had a "YTP" sort of effect, took me out of the immersion a bit), but then I just accepted it.
The puzzles are great and perfectly crafted: the "only found in the sky" one had me looking at the ceiling for a while, but then I remembered there IS a sky somewhere else...I'll not tell where not to spoil the experience for someone reading this. The fact there are red herrings that can be actually spotted is also perfect to make the puzzles balanced.
As for the final nitpick, I found the mouse sensitivity to be a bit low, it could be nice having an options to modify its speed. Also I found a small bug in the photo album near the end: if you click >, reach the end, and click <, you will not able to click > again except by exiting and clicking the book again.
Overall, a greatly polished games, with some small imperfections that can be easily fixed. Also, has a lot of potential to be expanded into a bigger game, in my opinion! :D
Really didn't expect to get told the story of [REDACTED] (go play the game to know more) :)
