Set friction to zero, and find the sweet spot where they move slowest. Watch as undying pixels float across the screen. It's like fireflies in the summer, fireworks in slow motion, or something magical.
For level 10, you'll need a function that can walk that s-shape on flat ground and up the stairs. There's no penalty for making your robot run into walls or jump randomly. Good luck. This is actually the hardest level despite not being the last.
#46 Corpse Looper - On floor 4, step next to the red teleporter at the bottom. Jump onto the launcher above. You'll fly up into the teleporter at the top, get sent to the bottom, and continue looping. Once you pick up a good amount of speed, hit panic. Achievement unlocked.
To get a massive speed boost in survival, upgrade your potion to ghost. Next, you'll have to get lucky and drink a potion with the level 3 horn at the same time. There's a bazillion little fuzz balls to kill, and each one of them will add to your speed. I've gotten up to 1,100 on my speedometer. If you can maintain that speed, the hard badge should be a breeze from here.
