Prime Jump is a minimalist high score chaser. Avoid the skeleton boxes and collect batteries (to unlock characters) by using 3 actions:1. Jump - tap the right half of the screen.2. Reverse gravity - tap the left half of the screen.3. Swing - tap anywhere when the character is at the same level as the next platform (this requires fast reflexes). This ability is used to get onto the bottom side of the next platform or to stop the character from falling.
