I love that you have a README and License file (main criteria for open source category).
Enjoying the fact that the game goes full screen by default. Love that you were able to implement keyboard, mouse, and gamepad controls. Nice work! The graphics are super cute (bunny is so cute), the sound effects and music are chill and fit nicely with your game. The carrot cannon is very funny; love it, sometimes the collision controls aren't the best (ie. the carrot would go through the fox rather than hitting it). Very minor however and doesn't impede the gameplay a whole lot. Nice work on the game and it's fun and addictive to play.
The animation for falling off is rather funny, kudos.
