I just played the web version. seemed ok. (on safari browser)
Interesting experience. I like the long interludes with the player characters arriving into the fight. I liked the ghost-flame character walking around the castle. All very charming.
It felt like the fighting was intended to be straightforward in order to match the pixel art. Normally I would say "add more juice", but I don't think this aesthetic warrants extreme juiciness.
Good game.
