Great idea and the graphics are superb! I did have a bit of trouble reading the numbers though :) I also got confused on my first couple of tries and thought setting off the mines was the same as marking them (before I realized you just avoid them instead of marking them safe). One problem with having a character traversing the minefield is that they sometimes block the numbers from view, but it never caused me any issues as I could always just step out of the way. A really impressive result for a 7 day project!
