There are five power-ups that can help you get ahead in this game:
Magnet - automatically draws all gems and coins to you, even if you're not touching them.
Embiggenate - temporarily triples your character size so you can grab more stuff and hit enemies with ease.
Fireball - allows you to shoot higher temporarily, while blazing through any enemies that may get in your path.
Double Score - does exactly as you'd expect, doubling your points for a limited amount of time.
Mega Mode - activates when you collect a significant number of coins and power-ups, making you invincible and shooting you higher than any of the previous power-ups.
Keep in mind you can level any of these up in the upgrades menu, with the first upgrade costing you 250 coins and rising exponentially after that.
