As said below its very easy, I beat Insane on my 3rd try. I got past the 1st level on insane every try. You just need to have some basic gaming backround. That sounds very nerdy heh. Anyway heres a screenshot on the end game on insane. http://img78.photobucket.com/albums/v291/It8ichy42/Own3d.jp
Even on older computers all you have to do is just hit nitro on the bat and hit the left and right buttons a good deal...
I dont know how far some of you went but there is a boss. I beat with game with the top ship and weapon and with over 400000 points, ending screen only shows only credits. The boss would be really hard without the last ship since it so fast and the boss hits hard but I won without to much of a problem. It ends on level 10, good job.
