Loved the game
Gorgeous, fun, and challenging without being prohibitively difficult.
I only have one technical complaint, which is in all likelihood NG's fault and not yours. I've now gone through the entire game four times, getting every death each time (I even double checked the walkthrough on my third time through to make sure), and I still haven't received the Grimm Master medal. I'm even playing it in popout and in the main browser. Dunno what's going on, but those last 100 points are taunting me.
