I love the artstyle SO MUCH, I went until the "powerfull ghosts" introduction's day, but from there it was a bit to hard for me, I'm happy I pushed until there, cause the designs of the ghost are amazing, and their mechanics are really interesting! The main issue I had was that ghosts were too attracted to me, our wapon isn't melee attack so their "attitude" don't really complement the gameplay? Maybe it would've been more suiting if most of them were running away from the player, attacking only from afar? Or maybe acting a bit like Mario's ghost: running away when we watch them, but coming at us when we have our back turned?
But dang the work it may have required, all those dialogues line (really fun too), the polish art style, multiple design, and all those mechanics! I know you were 3, but did you even sleep??
I would love to play that game again if you choose to work more on it after the jam!
