It's pretty good, a few things that I think would make it better is:

• Add a way for the player to score or add a stopwatch timer and record how long the player can go.
• Add obstacles the player should avoid.
• Add some SFX to make it less quiet. Bfxr is good for simple sounds.
• Add some music maybe, Bosca Ceoil is good for this.
• Make the level randomized if possible unless it already is if so, good.
• Make the ball/circle roll rather than just slide. (Basically rotation).

You have a good basis to work off of, and you can make something interesting with this.
