Be a fruit locked in a room, dodge circular saws and paint as much of the level as you can.
Each of the 12 fruits available has their own level with its little quirks. For each level your score is defined by how many of the tiles you managed to paint before getting sliced to death.
Your best score for each level adds up to your total metascore, which unlocks new fruits and difficulties. Easy and normal modes are unlocked from the start.
Additionally, in battle mode you may select one fruit and attempt to beat all the other fruits in continuous 1-to-1 face-offs. Will you bring your fruit to the King of Fruits status?
