Impossible to get very far in this game!

This game is fun, however its basically impossible to get past level 1 with the amount of "energy" (hearts) available to get in the game (without purchasing extra.)
Its very frustrating when youre doing everything right, but die because you go a long stretch without being offered any hearts for energy. I think Ill be deleting this one.
