Great game!
Great gameplay and graphics. I did find that on most of the levels I could just put all the explosives on the one weakest point and I'd get master blaster or excellent. However on level 35, after the game was starting to seem pretty easy, I can get really close but not quite over the line. So unfortunately I stopped playing there.
I really think the games like this should not have a brick wall in the game play where if there's one little part you can't get past that the entire rest of the game may as well have never been written. There ought to be a way to side step3 or so levels so you can still play even if you get stuck somewhere.
