Great title screen and opening music. The character arts are nice but the one frame of the blurred mouth during the speaking animation throws me off a bit, although maybe that's intentional. I found the speech audio to be a little irritating during the scenes with no background audio. Some of the audio is incredibly off balanced (reading the note on Carla's shelf in particular jumpscared me), but all of the music is very nice and appropriate to the scenes.
The minigames are fun and make nice interludes to the dialogs, I especially liked the last one. You may want to consider a motion sickness warning, as the 'water' scenes really got to me visually. Story wise it felt like the parents were the really horrifying thing about this situation. Overall, great tone, atmosphere, and pacing. Nice work!
