meh.
Nothing new here. 5x seems a bit steep...took me a few tries to get there. The "shoot green lines" really slowed my comp. down at about 4.2 and higher (showing 97-99% usage, core 2 duo). That actually helped get the badge though, so I guess I can't complain!
level 8 is not impossible...but pretty darn close to it. Hope you have a good memory; if you don't chances are you won't be finishing this one. At least getting the final crab is easy (assuming you get there!)
I wrote a really great intro, then got stuck...
