Congratulations for your first game! I feel this game is really cute and your choice of assets have really made a charming game that I think will do well played in the festival. Your level design is challenging enough but accessible for a range of player skills and has distinct scenes and setting that keep the game interesting. I like your use of sound effects, the fall sound effect gives me the nostalgia of arcade games.
For future games, it might be an idea to implement additional effects when you win the game completely to generate a 'feel good' feeling for the player and have a reward for collecting the fruit, such as a highscore or a method of spending them.
I look forward to seeing what you'll do next!
