Hi! Sorry for the late reply, unfortunately I'm not familiar with The Witch's House MV and RPG maker, so I'm afraid I can't help much here...
Hi! The Witch's House MV is a short game and I mentioned it just for the mood I'd like the game to have. It is not necessary to have played it ;)
About RPG Maker, it is not necessary either, since I'll do the events. I was looking more for someone who could help me thinking about the puzzles.
Here the trailer of The Witch's House.
If you are still not interested, no problem ;)
