Pretty cool. Though I feel like the controls would've been better if instead of WASD to walk it worked like Magicka 2, where you hold a mouse button to walk towards where your mouse is. That way you can walk and load spells simultaneously, which would make it better for taking a better look at other combos besides acting like a turret and spamming 1 and 2 together.
Cute and Little hard.
About bad ending... is not bad end?)
