I nice submission for your first game! I loved the art and style of the game!
Heres some feedback, and help on how to improve it:
- Make sure to add a controls menu that explains how to play the game
- Next time, for music, you can follow a tutorial like this one https://www.youtube.com/watch?v=JKoBWBXVvKY to play the audio seamlessly across scenes
- You could add a final goal, or coins to incentivize the player
