Tap and move your finger to control the game. You can change starting speed in menu. You don't need to start from 100 each time. You start the game with ten ships, with ships being your form of energy. Each run through the accelerator uses one ship, and one ship takes fifteen minutes to restore. Your ship can be repaired only three times per gameplay. To restore your ships for free set the time ahead on your phone or tablet. Set the time ahead fifteen minutes for every one ship that you've lost, or 2 1/2 hours to go from empty to full. Try to stay in the middle of the screen especially when you spend coins to restart. Pause the game at any time and you can increase or decrease the sensitivity of the swipe controls from the pause menu. A higher sensitivity works well in the faster parts of the collider in order to make swifter transitions from one side to the other. A lower sensitivity is better for accuracy.
