Got all the endings. FYI there is an ending that is unlocked by typing the dev's username (cheng3939) for the account ID. I think that is the only ending that is not that obvious from the game, but otherwise you can unlock everything else just by exploring.
Very good game, but you really need to make the other moves have some use because one move for each character is better than the other moves of the character so you are only going to spam that one move all the time and not use anything else. Maybe add some effects to the other moves like one move can be pure damage and have the highest damage output, but another move can do a status effect like stun the enemy for 1 turn or put poison on the enemy but have low damage. That way all the moves can be used based on the situation.
When you inspect the arrow after saving the king, dont do it while you are standing behind the chair... It will SOFTLOCK the game and you will have to refresh the page (basically ruining your progress)... UPVOTE SO PEOPLE CAN KNOW!!
