Pretty amusing game! I love the way it encourages the player to keep trying to get his objective, making it easy to spend long times concentrated on it and entertained.
Some things I would personally include so as to improving the experience:
-Some kind of panoramic view that allows the player to see further, as it sometimes gets bothering not knowing where to jump. As a suggestion, it could be included as another ability to be gathered in game.
-To give any utility to the coins/points earned in game, such as buying customizing items and/or abilities. That way, the player would rather try to take all the coins instead of just passing by to complete the game.
