i dug the basic idea and whole future dystopic setting. the graphics and shaders you used looked very nice, however they were very distracting, not just when looking around, but particularly regarding the game's one and only real mechanic.
morse code puzzle is a fun idea, but with the way it's staged it's impossible to see the puzzle and the morse code guide, and the keyboard at the same time. in fact, the shader actively made it unreadable if i tried to have both in view. it was only by typing into a web tool that i could solve it reasonably. a more fleshed out version might have progressive bits that teach you morse code in small bits until you get to a puzzle like the one you have. check out 'the witness' for a game that does this sort of thing very well.
would've been nice to see a little more twist in the revelation. in this case it was exactly as expected, and didn't really payoff the difficulty. i know it's not quite fair, but this sort of thing has been mined to death so much in every media that you see it a mile away.
so find a way to have the whole puzzle in view: keyboard, clue, and solution because asking to recognize, type, and decode all at once is literally a skill that takes weeks of training.
great effort!
