Hard Arcade Mode question
So I just beat the game selecting hard on each section, in one sitting and in under 60 minutes....but I didn't get any of the achievements or unlock gold sparkster mode.
Do you have to "unlock" hard mode for each section again in a single play-through for it to count? I know I got the first two in the run but I'm not sure I got Axel with his own purple attack (but just to clarify I have before and have unlocked every section's hard mode).
I'm either unlucky or really unlucky (just missed the achievements versus just missing the one boss unlock in case you were wondering) and could use some input from anyone that has unlocked these.
