Basalt Breaker

You made it -- you got a job at HeXaCo -- the alchemy factory that produces HexCores that power magical apparatuses. In this isometric minesweeper variant, your job is to flag for extraction the basalt columns that produced viable cores, clear the non-productive columns, and avoid setting off a dangerous explosion triggered by disturbing core-bearing columns. We even have a protection feature that offers a limited number of protected guesses when your goblin brain reaches an impasse.
