To move around, just use the arrow keys. To bounce, run into the wall on the right. To change where you bounce, touch the top or bottom of the screen and then run into the right wall.
I don't know why it won't work when you run into the left wall at first, and even when I tried to fix it, it didn't work. @TheConqueror345 helped with a lot of the coding. I would also like to give credit to Toby Fox for the music.
