KDR:  Not just Bomb Types.  
1)The Shake Items for defense are all mutual abilities:  Turn into Bomb (which is really cool), Jetpack (Somewhat cool), and Shield (Annoying) 
2)Also, I found if I had the line bomb I could not use the pickup bomb ability.  Perhaps I just didn't do it right, but that is what I am trying to figure out.  
I think they may have made the game to where you can't just become this impossible Super-powered Bomber.  Which I like.  
Finally, what I HATE, HATE, HATE is the slower animations that just slow the entire game down.  Punching glove is useless, because where it used to be a fast reaction to get bombs away from you...the animation is slow and turns it into a liability.
