Does anyone know the name of this iPhone game?

Ok, so I guess it's a little like Doodle Jump, I guess. You're this little blue blob creature, and you use accelerometer or touch control to move around on different platforms: one makes you bigger and slower and other one makes you smaller and move alot faster. There's fire at the bottom of the screen and spikes at the top, so you can't go too far up or down. It's been bothering me for so long. Thanks in advance!
