phew...
alright, I think I fixed this new one!
as for saving mid-battle, it's a little finicky. It's more stable if you save during your turn, without any animations running, but it's not a guarantee.
oh this is embarrassing... ;-;I (think) I've fixed this one now, sorry for the inconvenience!
thank you! the steam demo has been updated accordingly!
If you find a bug, please screenshot and report it!
