Phew! Ok, I agree, it's kinda hard but it kept me trying. You want to keep the money you collected so hard. Especially as I saw the highscores, this was a good incentive.
Although the music is all dreamy and relaxing, the game is on the other side! In a good way:) If the music would be like the game (thrilling and thriving) I would have turn it of, but now it is a good juxtapose.
I liked the idea and the graphics, the color change, the rain, the cute little hopping rabbit. Especially loved how you can immediately start the game again by just moving to the block. This kept me a while, a game over screen and a button to play again would have not.
As packers848848 mentioned, you could add the line you wrote in your Author Comments in the game, right under the place where the rabbit hops. The controls are kinda difficult since I easily slide under a part of the column as it comes down. The moving should be more accurate. Nevertheless, I enjoyed it.
