NeonballAuthor : Newgrounds - 14 300 plays
In Neonball, control a little luminous ball and jump from one neon light to the next to cross the levels and reach the exit. The challenge is to be as quick as possible and complete each level before the reference time runs out. To score as many points as you can, collect all of the stars on each level too, but watch out, as the levels get harder and harder as you advance through the game.
