It's pretty fun! Took a little getting used to what's going on and how to play the game, but learning it all was rewarding, especially since I died pretty easily and frequently in the beginning. xD

Increasing the size of the magic projectiles or its particle trail would be a nice addition - just so that they're easier to see. 

Overall, awesome job! Your engine works really well! :)

Neat little game, would be nice to have some more animation on walking maybe an animation when you alert the guards as well.

Took me a while to get into, because I was treating it like a typical top-down shooter when it's a bit more methodical and strategic than that. Once I got into a play style I liked, that seemed to work, I had a good time with it! GG indeed.
