here we go
I dubbed it level 7 (level 6 is still in the works)
3 problems
a) I wanted all asteroids save for the giants to have low stats, apparently planet size is based on stats so there is no way to control randomly generated stats
b) couldn't get the grace peroid to quite work for one of the maurading giants, it just adds to the fun

c)still no way to add custom levels to the menu, I replaced it with level 2. you might want to back up the stock level unzip and drop it in the resources folder. Select level 2 from the menu, you'll know it worked if a new screen popped up.
Caution this level is hard. I've beat it but lost more times than I've won. Still tweaking the variables
