Thank you for your comment.
I would have liked to create more levels, but being new to game development, I didn't know how to implement a tile system. As a result, I had to place each tile manually, which made it particularly difficult to create additional maps.
The issue with the music is that I didn't configure a "MusicManager" for the map music, and for some reason, when you export a Godot 4 project to web format, the music doesn't loop properly (very annoying).
I also considered adding a save point system since my brother had trouble progressing through the game, but I didn't have enough time to implement it.
If you're interested in the music, I found it on Pixabay. I really enjoyed browsing through the sounds they offer.
I plan to continue working on this project to add a few more levels and will update it on itch.io.
I appreciate you checking out my game and taking a moment to leave a comment.
