I really liked this entry - I haven't seen a card based battle mechanic like this before and it worked really effectively. It was quite difficult with some of the monsters, but since you could run away and leave those monsters marked on the map it wasn't too bad. I died after only exploring a quarter of the map but took on too many monsters :P
The music and sfx were also simple yet effective, and the simple graphics worked well. Very impressive that you did it all on your own!
Well done
