This version is more awesome and I've added some effects, and more levels! Yes, you can press the RIGHT or LEFT key and the UP key to climb a wall or climb the ceiling. You can change the song by pressing the space key and also the figure and color of the character. Note: In the first version you can also climb the walls and ceiling, but I didn't make levels for that.
