The artwork for this is very well done! The cutesy aesthetic of the phone and UI make it look like a dating sim character placed in Resident Evil or Kings Field.
I like the concept of the various artifacts changing the environment (however that would work). And the character mentioning a target combined with the more PSX horror looking inventory items hints at a darker world in a nice way. I'd almost imagine this as a sort of contained open world where you could wander a section of a city, with lots of secrets to be found by manipulating the environment. Even if that's nowhere near your idea, you succeeded in making my brain desire to learn more.
Good stuff!
