Level  53 is probably solvable, but it's too annoying
Level  57 is probably solvable, but it's too annoying
Level  61 is not solvable -- with magic wheel timer set to 0, cannot get past or explode exit-blocking robots
Level  76 is not solvable -- at least one emerald is exploded unless bombs at [48,18], [52,15] and [54,9] are rocks (except there's a reachable easy-out open exit at [35,27])
