I really like the music choices and think the tutorial cards are quite lovely. But, I do think maybe there's too much all at once being given to the player. With it being a jam, that makes sense, but maybe try and slow down how much you're teaching the player at once and how many people / places they get to know within the first 30 minutes.
The battle HUD is gorgeous and I love the use of color in your skill descriptions. I also liked your mapping!
I will say, I think your title card is INCREDIBLY misleading -- I would've skipped over your game if I were just scrolling bc the font / gem combo makes it look like a mobile gacha game, rather than the really well-developed RPG that it is and I would've been really sad to miss this one!
Are you planning on continuing to develop this? I'd love to keep up with your dev on it, if so! :)
