Near end, but lost
First -- just a great game.
Second -- I just don't know what I should do next. Can anyone nudge me in the right direction? Here's my status:
I've been to six parts of the world (Volcano, Race Track, etc.), including the End Zone. It feels as though I've explored everything (except the End Zone) pretty thoroughly.... ten or twelve times... but missed some things....
Weapons: Super pellets; Super beam; Wave and homing (not super for either)
So I'm thinking that I need to upgrade the remaining wave and homing, then I'll be ready for the End Zone. Is that right?
Also, I can see the weapon upgrade in the southeast part of the volcano, but can't figure out how to knock out the plates that block access to the upgrade, and the skull shooter thingy always smites me. Can't find the other weapon upgrade whatsoever.
So I'm stuck. I'd appreciate any advice - thanks!
