Surprisingly unique set-up, immersive sequences throughout, yet the game's main puzzle is directionless.
I have to point out that for your first game, this is amazing. The game presents itself with a mysterious tone, superb atmosphere, really unique interactions with the door and then again the sequence with the stairs. I loved all that.
Although, the main puzzle with the numbers seemed directionless. What you want in your game is to create a game from a player's perspective, hence the player doesn't know the underlying meaning behind the puzzle and you should explain to them, even slightly so, what it is about. The note draws similarity to the Matthew verse, but doesn't fully embrace the idea behind it. Not to mention, most people won't understand the reference, so you have to give them a chance either way. Thinking that a player will understand your perspective is not so good in game development, trust me, I know. Otherwise, the game has a performance issue, lags in couple of places. In short, good game, but needs an update for sure.
Best of luck with the future projects!
