I liked the art style, it's very good
But I have a couple problems...
First one is a technical problem. The direction of the attack range you control with mouse, needs to be fixed. Since it gets the rotation by taking the distance from character to the mouse pointer, it rotates when the character moves. And this is not beneficial during combat.
Secondly, starting the timer after entering the castle could be a better idea. Because it lets the player to get used to controls and appreciate the art style this game has without pressure.
And finally, because the game is repetitive, seeing that cutscene at the beginning over and over again made me frustrated. It would be great to have a button that skips all of them.
I wish you luck and I hope the game becomes better in future.
