Minesweeper - Bird o' Mine

Bird o' Mine is a logic puzzle in which you use math to clear the minefield. Make 1 mistake - boom.
You and your birds have to track down landmines, using logical thinking and math. When you step on a cube, a number shows up above the bird that indicates how many mines surround you.
By cautiously navigating through the minefield, you are able to detect which cubes have mines, and walk on the ones that aren't.
A level is completed once you've detected all the mines, and stepped on the cubes that aren't explosive.
