Color Dreams actually did something right!
Now to the game play. You control a robot on the moon or something mining for diamonds and such. It has a weird top/side view that is actually quite effective. You run through the levels trying to blow your way through obstacles and running from mud monsters. The whole game has a weird gravitational pull that pulls boulders and diamonds down, and if you do it right, you can crush your enemies with boulders, but you can also get crushed yourself. It is very challenging, but very satisfying. The later levels get progressively harder, as you have to stay away from lava and radioactive deposits. In all, it is a great game in the NES library, and I highly recommend it for anyone who is a fan of puzzle games.
