How to play:
– Move bunny left and right with mouse to control bunny’s position
– All things have to touch bunny’s mouth to be effective
– Collect hearts to gain points
– Collect carrots to store as lives
– Carrots save the bunny when bomb hits the bunny
– Bomb takes away bunny’s lives and deduct 10 heart points
– Bunny dies when heart point is -100 or when bomb hits bunny and there is no carrot to save bunny

Statement:
For my project, I decided to create a game that involves a bunny and heart rain. I wanted to create a simple, cute game that people can play with. Hearts are points and the carrots are lives. The bomb is what kills the bunny. The player should aim to gain as many heart points as possible. The stored carrots save the bunny from dying in the case that the bomb hits the bunny. I made the bomb fall fast on purpose so that it will be harder to escape the bomb, adding some excitement to the game. I also made the carrots, which rarely appears (to make the carrots more precious), fall fast. 10 heart points are deducted if the bunny hits the bomb. This is so that the player can’t keep using carrots to save the bunny while not collecting hearts. I made the background simple for this game as because of the “glittering effect” of the heart and the movement of the things falling, having more complicated background will confuse the player’s eyes too much. Initially, I made the hearts simply pink, but then I thought that was too boring and so I changed my codes so that they change colors randomly to create a glittering effect. The things have to touch the bunny’s mouth to be effective as my idea is that the bunny “eats” the things to collect them. For my codes, I used a lot of nested functions to make my codes clearer and easier to manipulate. I had a lot of fun creating this project as I have always wanted to create a cute game with movements of hearts that people can play with that cheers them up on bad days.
