First of all thanks for playing and taking the time to write feedback (=
-All the puzzles are solveable without knowledge outside the game, knowing a bit about Kubrick makes the first puzzle easier but all 3 hints lead to the same number.
-Sorry for the inconvenience with the deaths, the original intend was to close the game there but it didnt translate well into the browser version, resetting the game to the start without reloading the page would sadly take a lot of time i dont really have currently due to the way i handled the ingame events
-Not sure what you mean about the numbers in the dark, since you saw the ending you seem to have solved it so you should now why the numbers are different each time
-The dialogue you mentioned onyl triggers after a set amount of time, the mirror doesnt kill you before you get warned about it sinc ei thought that would be too unfair
