Gunhound EX (PSP) Impressions

I finally opened Gunhound EX which I got back around Valentine's.  It is a doujin PC game ported to PSP by GRev.  It is a love letter to the Assault Suit Valken games.  The first level is pretty dang awesome.  The second level is almost impossibly hard unless I am missing a big thing.  See it is an escort mission with forced scrolling.  This snake thing is coming up from behind and I can' go meet it so it just ends up in my escorting thing and wrecks it before I can murder it.  I'm not even sure I can murder it.  It is hard.  Game is conflicting.
