Very interesting!! Played it twice, and funnily enough, I actually did get more information the second time around. Played it first using a trackpad, and second using a stylus, and interestingly, the stylus brought me more frustration as clicks would make the cursor jump up a bit, making it go out of bounds, and restarting the level lol.
Spoilers:
I love that you can't tell that the...uh...skull crab? is outside until it moves, and in the first playthrough it definitely was hard to distinguish, definitely adding to the suspense. I also loved that unlocking the key in the game caused your door to unlock, like a digital-age Dracula asking you to allow him to come in by tricking you. The fact that the game begins by asking you permission to your visual cortex, which seemingly is so that the game can prevent you from being able to turn around unless clicking the relevant button in the game. Lastly, I only got this the second time around, but the player dies to then become one of the skull crabs, which is pretty sick
