Cute looking game, I like music and detailed animations.
But on balance department there are some issues. No point to use anything, but fast slash attack because of its insane dps, like I killed bosses 2 and 4 without even getting what they were doing, because they died too fast. So definitely need to nerf it and add more love to other attacks.
Dialog-wise, I wouldn't mind to read the lore, but without option to immediately show the text it becomes a bit tiresome, cuz you need to wait for the text to be typed out.
