Fixed! Changed the trail fade from `0.2` to `0.05` in index.html:57. The lower alpha value means the previous frames fade more slowly, creating a longer, more visible trail effect.

**Next Ideas:**
1. **Trail Color Shift** - Make the trail retain the color of the ball as it moves, creating a rainbow path
2. **Xbox Controller Support** - Add analog stick control to manually influence the ball's velocity for interactive play
