Yes the seven "ball messages" are for 20k intervals; that is: 0-20k, 20k-40k, 40k-60k, 60k-80k, 80k-100k, 100k-120k, 120k+.

Combo Breaker was difficult until I realized what the green orbs did. (lern 2 reed gooderer?) They spawn new things to hit, so go for the green orbs and eventually the screen will be so full of orbs that you get the medal.  The rubbery blocks count towards combos. Hitting the outer wall DOES break the combo.

Determination required me to play 2 more games after the original 10. It popped up after I suicided a couple times, so perhaps the 0 points medal needs to be done repeatedly? Or the Grandma one.

Either way, 15 mins and 200+ points, fine by me.

Oh, I also used speedhack 0.5, helps a bit.

Phren if you have a chance, can you tell me where you found those?

I'm sorry for asking but I really don't understand why you just have one AOB instead of how I usually see it where you change it to something else. I'm assuming you find the easiest AOB and change that to the other medal AOB's you need. Am I correct? Or is there a faster way because that involves lot's of refreshing.
