What was the hardest moment for you in SPG??
I never had problems with any stage (even the Trial Galaxies were easy, except the last round of bubble) but I had problems with one.
Well... I can say officially I hate that stage. I had 119 stars,,, and the 120th was Purple Coins... Darn... I've lost around 50 lives... I hated that stage so much... once, I died in the last jump, when you have 99 coins...
