It´s impressive that one person did this.
The athmosphere is nicely set up with the intro and outro voice over and some of the jump scares got me good.
But good puzzle games are hard to make so a lot of times I felt a bit lost and did not know what to do and what the symbols mean, so maybe some more hints and information for the player would have be nice even though in total it was not that challenging but instead a bit frustrating at times if you just do try and error until something works for a good while.
Props for attempting the challenge and I like your concept for the game. You have done well Sir! ^^
