Start the game: Press the Green Flag and press a space key to play this game ,choose how high you throw it by how long you hold space. it's hard in the beginning but first practice to gain skill points which makes you better! also don't wear out your hand too much (in game ,not real life)! Bug : If you constantly make hand power 0 for long, you have a small chance of breaking/injuring your hand in which hand power will be 0 forever
