oh this was just FANTASTIC. so unique and original and extremely well made! :D
(SPOILERS)
the retro vibes are absolutely on point. the excellent use of pixelart, the few pieces of music and the credits song, the filter that seems to slightly blur the screen... everything came together at the start to make me feel like i was playing a game from the 80s haha. it's a really tricky aesthetic to pull off without breaking immersion... until you get to this creepy office and suddenly the immersion is broken in the best possible way. the uncannily realistic sounds of machines and computers and the phone call that breaks the fourth wall gave me so much whiplash, it deadass felt like something you'd see in undertale or ddlc. just excellent use of tone.
speaking of art and sounds, they were both amazing!! everything looks really clean and has a nice balance of simple enough to know what you're looking at and detailed enough to look oddly realistic (those chalk drawings on the ground were a highlight haha, such a cute detail). really love the color palette too, it's dark and moody but it never felt boring. and the SOUND DESIGN my god. incredible mix of retro videogame-y sfx and drony office white noise. i said it before but walking through those halls with the sounds of random machines turning on and off was sooo uncanny. and the song at the credits was so good! don't know if it's original or not (if it says in the credits i missed it sorry) but kudos for either making it or choosing it haha.
the puzzles were really clever! none felt unfair or too hard, and even if i got stuck at any point there's not that much stuff to interact with so it didn't take long to find what i needed to do. i think maybe the phone in the number room blended a bit too much with the background, i only noticed it when i interacted with it by accident lol. oh and of course... the file puzzle!!! so so so cool. such a fun way to break the fourth wall haha. and i played this game twice (the second time cuz i saw it got updated) so i checked because i was curious and THE FILE GETS CREATED ON ITS OWN??? I THOUGHT IT WAS JUST THERE THE WHOLE TIME???? ungodly awesome haha :D
the plot seems very interesting! i like how abstract it feels, like even if you don't follow what's happening, you understand that it's supposed to be intense. the conversation (or monologue?) at the end was really well written and made me ask so many questions. i was REALLY invested in finding out what was actually happening.
but what i truly think makes this game come together the way it does, is the incredible attention to detail on everything here... the way the text moves and vibrates during certain scenes, the way it changes color depending on what machine you're using, the way it skips in the final monologue, the camera zooming in when you have to mash z, the character becoming faceless in the last stretch, how fluidly the screen moves, the sounds that appear with each letter of each text showing up, when the credits end and the main character shows up sleeping in an incredibly creepy but also kinda soothing way (reminded me of the sleeping dog at the end of undertale haha)... all of these small things make this game feel like it was treated with immense care and attention, and i really admire it :D
if i had to mention any problems i had, i found two bugs across my two playthroughs (tho the first one didn't happen the second time i played so i guess you've already fixed it): one where i was stuck outside the map when transported to the ending cutscene room; and another when after beating the game, i pressed on "log in" and it took me to the scene of the mc sleeping, except the bed was upside down until the character appeared. i know this game is really short but i'd suggest adding a way to save, just so unexpected softlocking bugs like the one i had aren't that annoying? that's just my opinion tho.
overall, this game was amazing. an absurdly well crafted piece of horror and uneasiness. i really hope you work on the full game, cuz you've left me intrigued as all heck and just this demo has already shown so many incredible displays of talent. great job!! :>
