Thanks for the feedback. I was originally working on 3D models and spent a lot of time learning programming and using engines like Unity. Finally, I switched to Godot. This is my first game loop that I have successfully created 😁.
On the graphics side, I spent some time searching Pinterest for patterns of interest using the search term isometics. For the music, as I mentioned, there was some AI involved, so I tried to generate them based on the concept of a Casual game.
