I see your confused about why Shatter is killing you in your Bubble. I'll explain. So with shatter, you have the capability to turn the screen while activating your nova bomb so the 3 particals can be closer or farther away from each other (righty tighty, lefty loosy). The people with shatter on destroy your bubble by specifically placing two particals on your bubble (which destroys it), and the last one outside which kills everyone that was inside. :P
