Main menu looks good. The mouse is not visible on start, so I had to use the Windows key to reveal the mouse.
The narrative and objective is made clear through the cutscenes and notes.
Game can be slightly laggy, an FPS limit could be good.
Tutorial is clear, and I was comfortable with the controls by the end. Melee combat is good, and spells work well (though didn't feel the need to use them much until the end). Potions work well (but stack up quick). The dash is extremely useful, maybe too useful. I was able to travel through the world quickly because of this, and this made the exploding enemies extremely easy to beat. Maybe a cooldown, or tying this to the special meter might balance this.
The melee enemies damage hit box seems to be active too long. For example, when dashing away and immediately dashing back post-attack, I occasionally took damage. A timer linked to swimming is strange, maybe a oxygen bar instead?
Light beams in the sky are very useful. Good final battle, and well disguised.
Couldn't get the controller to work for this game.
