This games reminds a bit of Doodle Jump, not sure why. It's amusing but the movement can be tricky, as a slight error make you fall or miss your target. Some UI Elements might need to be adjusted.
But still it's a Good Job!

When opening the game there are black bars on top and bottom. On top is is partially hiding the information about time and points and the Switch/fading when you die is doing the inverse the black bars on top are showing the rest of the screen.
Furthermore perhaps you should prevent that you can go out of the screen on the sides (but perhaps it is on purpose for the difficulty ;) ).
