Fun game, slick presentation, great art and music. Great choice of dungeon theme in particular.
As I mentioned in the server, I think it needs balancing, but frankly balancing an RPG for a jam is difficult, I understand.
I feel that the special skills cost too much for how little faith you can recover normally, and Sanae's move that recovers faith is not that useful most of the time. I feel the skills should cost only 25%. In addition , some items are pretty expensive. There's a way to recover faith and get free heals by fighting any enemy that deals zero damage to you and making use of those free turns, but I think that was not the intention... Something like a fountain or shrine midway through the dungeon that heals your HP/faith once would be pretty useful.
Finally, misfortune can sorta softlock you if you run out of money to heal yourself.
Now, two bugs. If you pick a move but don't pick a target, but rather escape, then you won't be able to act in the next battle until you reset the game. Also, you can heal your misfortune and end up with negative money; I'm not sure of the exact steps, but it happened after buying some items. I mention it as it seems you are planning an update.
Apologies for the long comment, I see a lot of potential in this game! I'm looking forward to the full version.
