So I came across a pretty big bug in the Windows version that seems to make progress impossible for me. After finding the Insect character, I went back to town, saved my game, switched to it and quit. When I wanted to play more a couple days later... this happened.
Any time I get to the castle entrance screen, my character is changed to the Witch - and the attack button doesn't work. Going back towards the village, I'm then changed to the Knight, who also cannot attack and no longer has a walking animation. All three characters are in the village and I can change to them but it just happens again, even when I'm the Witch I lose my ability to attack (and my cat) any time I reach the castle entrance.
So. Yeah. No idea what might be causing this.
Edit: The bug persists through saving at the castle entrance, exiting and restarting the game too.
