Cool concept. It seems to me that it rely too much on luck. Some times you must take some risk to keep your health. The selection system is strange at first, I think if you just remove the space 'confirmation' it will be smoother (there is already the bottom to cancel). I like the atmosphere of the game. Perhaps with some hint (like a min sweeper, but perhaps with audio hints) that tell you beware there is something near it could help reduce the randomness. Overall, good game.
