|Graphics didn't get any better...|
Explosions would chain, and bigger bombs had bigger explosions. You could still only run away one space, so manually detonating a big bomb was suicide. So the goal was to figure out the order to explode the bombs and the chains you wanted to have happen. I like puzzle games, and these puzzles were fairly interesting.
Unfortunately the interface was terrible. You died if you walked off the cliff, or got exploded. You'll note the board is set up with diagonal movement while the SNES controller is up/down and left/right. So sometimes I'd just walk off the cliff for no reason. Movement was also painfully slow, and the whole 'hold the button down for 3 seconds and then run' mechanic didn't seem to serve any purpose at all. Push a button to tag a bomb to explode when you walk off would seem to be a better interface. That way I wouldn't accidentally kill myself by mistiming things, which did happen. It also took forever to reload after a mistake.
On the plus side, it had actual speech to introduce the levels. Just 'Player One, Get Ready' in a very robotic female voice, but still pretty good for an SNES game. Minus points for being player one get ready instead of ready player one, though.
So while I like the idea of the game, and could see playing it as a browser game or something, the SNES game was painful to play.
