The Red Ball is the projectile. Click to launch projectile. The farther cursor/touch is away from ball, the faster it launches. Get to blue circle to proceed and avoid red spikes. Once the red ball has hit the wall after a launch, you may launch again.
Credits to cs502244, who is my previous account for the projectile physics. All levels tested by me. Tips: If you are going to use the wall-launch feature, hold the mouse/touch down to aim better. Still work in progress
