Agreed on the writing being unnecessarily cryptic. I think more straightforward writing would benefit just for the sake of readability and getting back to the gameplay. I'd glance over the dialogue, go "huh?" and reread it a couple times and have to translate it in my head to something more sensible, sort of like reading old English? If that makes sense. Needing to pause just for that extra second or two interrupts the flow for me, personally.
I understand wanting the vibe to be cryptic and mysterious, but the vibe is already cryptic and mysterious with everything else going on. The dialogue doesn't need it imo. Less is more here, I think.
The vibe is good, though. This is a nice simulation of an old Windows PC and the minigames for each form are satisfying to complete, varied enough to not be too mind-numbing, simple enough to be able to repeat them without getting carpal tunnel, and forgiving enough with good QoL that I don't hate doing them (such as locking the minigame when you've done it correctly). I found I was able to just run a line over my signature for 80%+ accuracy, and I appreciate the leniency in the signature detection for the sake of my wrist, I hope you keep that.
