The only part of the title of this game that I understand is the 'hard' part, because this game is really hard. If you want an impossible challenge then this is the game for you. You are a heart, for some reason and an important thing to know about this heart is that the only way it knows how to move it by jumping. How you make it do a small jump is still not clear. Collect all the red balls and complete the quest that is given to you in each level. Use the money you earn from destroying enemies in the shop.
