Seems almost impossible to avoid the Heart Stopper once he gets to the side of you. Also it seems like most of the power ups you are unable to pickup. The sound design is nice
Edit: thanks for the tip. I'll update my rating

Thank you for the comment! When the Heart Stopper is about to get you, you can go off-screen and come back at the other end of the line. This can also help you reach the power ups before the Heart Stopper does, but they are deliberately placed randomly in a rectangle near the centre of the screen so they're hard to get. To be honest, I think I should have added this screen-loop mechanic to the How To Play text.
