Played just past the dragon boss at the end of chapter 1.
Yeah, it actually reminds me of Defender because it has that little mini-map at the top of the screen. I kinda like the circular maps (reminds me of a Tekken arena or something), and how they have multiple exits to new areas, some of them entirely optional, but I am finding myself agreeing with Prole on the controls feeling a bit sluggish. I don't like how defending is mapped to the [] button, the same button as the attack button, nor do I much care for the zoomed in camera angle, which makes it hard to see what's going on around you.
But, OMG OMG OMG the graphics are to die for!
