Had a lot of fun with this! Visual novels aren't really in my wheelhouse to begin with, so it was fun to branch out and give it a shot.
POTENTIAL SPOILERS:
Would like to see some of the early story points expanded on - namely the brief mention of heirs disappearing. Also thought the housekeeper might have had a role beyond the opening sequence, but that's really more of a sidenote and not detrimental to the story at all.
Overall, I feel like the story was executed well. It did seem to drag a bit in places, but that might just come down to a matter of personal preference. It was an engaging narrative and provided plenty of details early on to get the player invested in uncovering the mystery.
Thanks for the experience!
