Pretty cute game, but the gameplay is clearly unfinished.
I got softlocked my first attempt against Aunn, but I don't think it's because I lost. I say I'm not sure, because it's quite hard to know if it's one Aunn or a fairy of light that got defeated when everything is displayed as <null>, but it was just turn 2, so I doubt the game is unforgiving enough that I'd be the one to lose. Maybe that happens when some of the fairy of light still have attack targeting a target that got defeated by an earlier attack this turn? Maybe something else.
