Interesting combination of action RPGs and card games. Like others have said, I definitely had some issues with enemies spawning too close or not getting to see them until it was too late to dodge them. Expanding the base area of vision would help a lot for this. The saving system also seemed odd to me, I would prefer a click to save/confirm dialogue rather than having to stand still to confirm saving.
The intro area is a bit too large, that's a lot of walking around doing nothing to get through the tutorial. It also would be a bit better to have some sort of music playing in the safe zone. For the core gameplay, the full circle attack feels great. I did have several times when my attack did not seem to register but I am on a laptoptouch pad so that may have been part of the problem.
Overall, solid game and feels like it has some real potential, just needs a little more polish.
