Good start. I know how frustrating Unreal's UI can be, but you'll need to figure out some things like moving images to the mouse cursor (it is possible). An issue is I found myself often target an enemy with a spell and instead moving somewhere I didn't want to. Hotkeys would be really cool too and maybe tying the camera rotation to moving the mouse to the edges of the screen. I liked the music and graphics, it had a peaceful feel.
