For anyone interested in Godot, I made a mobile first (Sailfish Os only) version https://github.com/poetaster/balldrop which is based on https://github.com/Bauxitedev/balldrop It was great simple problem set for solving touch screen problems in Godot and makes lovely melodies :)
And a youtube video of the original https://www.youtube.com/watch?v=yhKnGPcZmE4
