Just. Bloody. MARVELOUS. I've long been of the belief that simplicity in game design yields the greatest depth of play, and now it seems I have another shining star to which I can point for proof.
The only thing that I can see it to be lacking at this point is some option for remote co-op play, for those of us without roommates or nearby friends to operate the other side of the keyboard. Or maybe a separate option for solo players in which the bombs last for an extra warning beep before detonating. Or maybe I simply need to, as the kids say, "git gud". In any event, none of this is enough to detract from the value of the experience. You've more than earned every star.
