Man!! Man oh man I'm a sucker for these types of games and you executed on it beautifully! Such a tidy presentation and just a unique take on a project for a game jam. Leaning into your strengths and scoping to what you can achieve in the time really worked out here!
This kind of reminds me of Kingdom Ka with the pace and tone of writing, as well as the photo usage! Also a bit of Superliminal with its occasional narration about perception and perspective (and those themes being tied into the gameplay)
I did get stuck near the beginning but I saw the comments suggest there was more to the game and after the first 4 images (barring the third), I was able to follow along and intuit what I had to do to proceed without semi-random clicking! If you wanted some unwarranted suggestions as to make those earlier moments more graspable to player, some ideas knocked around in my head.
I drew fanart of one of the slides with the part of the narration that really resonated with me: 
Congrats on making your first game! It was fascinating and I'm excited to delve into your other work.

Holy crap thank you for this! What a cool drawing! I love the lil fella holding the B :) Also thanks for all the kind words, I had a lot of fun with making this, so all the positive feedback is a cherry on top. I'll have to look into Kingdom Ka, it sounds lovely. Thanks for your time and for sticking it out through the unclear images :)
