AMAZING job! I love speed and the setting, visual effects, and everything else were perfect. I fended off a few entities but one finally got me that I didn't see coming. Maybe it's part of the point (that you always have to grab the camera and look around) but it would be nice if you always either see an entity walking in the background (this I saw happen) or hear one walking somewhere. That way, you can focus on the card game until you see or hear something and then you have to try and find where it is, instead of just remembering to occasionally check around. Maybe that's exactly how it works already and I just missed a cue. Or maybe the point is that you're not always supposed to know when entities are there. Either way, great work!!
Edit: Oh, it would also be nice to be able to grab new cards with Tab!
