I played it and I like it. Cool level map!
The idea to use Minesweeper for skill-based battle is fun ^^ I was missing some info though how exactly the damage is calculated. Per correctly flagged mine? Per revealed slot?
The damage is the sum of the "number" tiles you reveal. Bombs only give you information on where the numbers are (And finish your turn if you find one). Flags are just a visual aid. I'll write this down so we can make it clearer next time! Thanks for playing :D
