Very cute art style, definitely the highlight of this game!
The controls were a bit confusing at first, since the page doesn't mention the mouse at all, so I thought WASD with the player facing to the right was just how you were supposed to play the game for some time. It might have been better suited to just stick to WASD, since the combat is simple enough that strafing wasn't really something that ever needed to come up. The platforming segments in the taller room with the isometric camera were also quite difficult, since it was difficult to tell how the next platform to jump to aligned with the previous.
