I think you have something here, I like the fact that we actually explore the map and I also really like the manor's music, remind me Isaac's OST ^^
But, still the games need more polishing in my humble opinion, is still has this prototype feeling in the UX
Also small note but I first though the player will have to manage each character's health as what can do a Darkest Dungeon for example, so I got a little surprised when I saw that the all team share the same health bar.
Keep going ! you're on the road of making such a good game, congratulation for the work done so far !
