Thanks for playing the game!
Yeah, this game is still quite incomplete (I'd say I am about 60% done with the original vision for this jam.)
As for the controls, let me see why you can't cast spells, since that can be an issue. (I am also planning on adding Gamepad controls.) I'll see why the mouse is not working.
Oh, I also forgot to mention that there is a boss fight. (If you are in the Level and press "B" keyboard key, you will be sent to the boss room, just in case you were interested in trying that!)
Maybe I should update the main page mentioning that little tid-bit. ^_^"
I appreciate the feedback! :D
