I had some graphical glitches (I don't have a 1920x1080 screen - maybe that's the cause).
I found it a bit too easy: The spell if pretty potent. Running through enemies spamming space is also too powerful. And I never used dash. I think dash would be useful if enemies had a larger attack radius and the player had some notification on whence an attack happens.
It could evolve into a nice dungeon-crawler with real-time combat though.
