What counts as powerups?
Solution 1:
The only powerups that break this are the Shield, Boost, and Coin Magnet. Activating anything other than that will still enable you to get this objective. You can also pick up gems and coins without fear.
Solution 2:
The circles in the air are power-ups, as is the power bar. You can still pick up gems, coins, and artifacts, without worrying about failing. Also, I belive if you die, and use the wheel, It will count as a power-up if you get a boost, coin magnet, ect.
