I have been developing games as an independent / individual programmer (without a sponsor / without advertising / everything free of charge) since September 2025 with "Godot". My grandchildren introduced me to “Sprunki”. However, you can only move symbols (drag & drop) to create melodies. I imagine a normal game in which you navigate the main character Polo through a 2D world (jump-and-run style, similar to Hollow Night in terms of movements), find abilities, defeat enemies, and collect points (notes) to develop the character and finally defeat a boss to advance to the next world, where you then become another Sprunki character... who then goes through the same logic as Polo until, in the end, the entire “orchestra” plays music again.
