The floating island and temple environments look great, and the combat feels pretty satisfying with the basic attacks, dodge, skills, and ultimate. The ultimate animation is a bit slow, but it's clear a lot of effort went into it.
One issue I had was the camera. It moves a little too quickly, and it frequently clips through the ground. It would be nice to have options to adjust the camera sensitivity and invert the camera controls.
Other than that, the main character's walking speed feels a bit too slow.
Also, when I died, I got sent to what seemed like a practice room and then ended up fighting the boss. I'm not sure if that's the intended progression or if something went wrong.
