The art is really cute, and I like the premise of a friendly exorcist! Also funny that the ghost is just there floating in the corner in the house right at the beginning.
Leaving the house felt kind of counter-intuitive, as you go up to exit the door, but you leave the house on the downside, so if you are still pressing up, you just go back in.
I just collected all the stuff from the house right away and when I talked to various characters around the house, the next dialogue option was already unlocked. Also noticed talking to person in the corner, half their speech bubble was off screen, wanted to read what they were saying!
