This is a great concept and I LOVE the art. Great take on the auto-shooter. The two side of the moon was also a ton of fun to play around with, I straddled the line most of the time.
Since it is in 3D it's a bit harder to position like it is Vampire Surivor. I struggled getting close enough and facing the right direction for the scratch a lot of the time. I would recommend some longer ranges for the attacks.
