I loved it! Easily one of my favourite submissions for this gamejam.
Obviously, writing is everything for this kind of game and it was excellent! I don't just mean the game dialogue in the game, I mean the description too. It was actually that which hooked me in first. Without knowing the context for the gamejam, one could be forgiven for believing it really is a product description for an AI. Mainly because there aren't any implications about how dangerous it is until the last bit. It identified your game as something very different from other submissions early on.
As for the game dialogue, it's very engaging indeed! You did an excellent job of making ELLA-M very relatable to (what I imagine) almost anybody from any culture. The question about whether the player has ever felt like they care more about the characters on a tv show than their actual friends and family was especially brilliant. At the same time, ELLA also seems equally inscrutable. It was a bit like watching an actor playing a trickster. Always wanting the audience to question their character's sincerity. Keeping them on their toes all the time. I even wonder if ELLA has something akin to D.I.D. where it's a system of personas that vary wildly in the amount of sympathy they have for humanity.
I do wish there'd been more variety in terms of audio. Like of course that's far from the most important facet for this and it certainly didn't ruin the experience. But I think it'd enhance the more dramatic moments of the game. Like if sounds accompanying ELLA's dialogue would change based on its sudden shifts in mood. Or it could be more subtle, like changing just for a moment when certain words appear to indicate to the audience that said words are key to deciphering ELLA's true intentions.
I think I like it enough to pay for a full version if you ever happen to create one.
