Very cool idea! It took me awhile to see where I was on the map, I actually noticed the trees before I noticed my player character hehe, so perhaps a little effect on the player would make it very clear!
The card design art and the map art is amazing! Really love the style~ Also the UI is superb! I kinda wished I could zoom in and out on the map, also the icons are quite tiny.
Perhaps a little linear tutorial at the start just to learn the basics would really help. Once it started I was a bit overwhelmed hehe.
Really neat idea and keep working on it!
