Thanks! Trying to find the cause of this bug, there is a tiny helper in the pause menu (press P or enter, there is a bug fix option).
UPD: uploaded a tiny fix. This issue should be gone now.
Hi. Today at 22nd of March I encountered the same bug. I would believe what got me stuck has something to do with my warrior dying and only having a mage left with no moves.
Otherwise, fun little game.
