Thank you for playing my game and sharing your score. I included you into the high-score-table. Congratulations, you are currently on rank 16. 144 points are a very good score considering that it was your first try. I am very curious, how high you can climb on the leaderboards!
Have you already tried the graphical version of RunToTheStairs? It looks much better, but requires a modern browser which is supporting WebGL 2.0.
