BOOM!
like the others, I agree that this is challenging and difficult at the same time
Level 30 is a toughy, and there are some on Elite that are pretty hard, but some of them are just remembering what you did before. I agree with DOOMbubble, shoulda had a cooler ending to it, but it was fun regardless. And I used my finger to remember where I had to throw the grenades haha.
*SPOILER*
after you beat elite, and you spam grenades everywhere...it just gets rediculous, does if effect your score though if you go back and do every level over again?
