Not much out there on this game so here you go:
There are SIX level altering mechanics that happen when you go on a RUN: You need to see all six of them before you die which means you're going to have to get pretty far AND rely on some RNG as the mechanics are completely random in terms of what you get and when.
The six are:
PLAY - happens automatically when you start.
FAST FORWARD - pretty common. speeds you up.
SLO MOTION - pretty common. slows you down.
REPEAT - less common. It repeats whatever obstacle you were on. Rather pointless.
NEW TRACK - the least common. It instantly creates a new obstacle course for you.
SHUFFLE - pretty common and an absolute run wrecker. It flips you to the top of the screen and you have to play upside down.
Your best best is to get a good drop on SHUFFLE. I'm one of the top platformer gamers on TA (not trying to brag I swear) but SHUFFLE wrecks me within 30-45 seconds. So you have to hope you get SHUFFLE first and then another SHUFFLE to immediately cancel it OR you have to hope you get SHUFFLE last and unlock the achievement before you die.
This will take many runs and RNG to work out for you.
GOOD LUCK!
