This weekend I've finished the sling minigame, I haven't tested it on touch screens, but should be perfect for those platforms while still playable with mouse.The game is in the attachments.
Sling minigame using touch or mouse drags. The code for this minigame will remain exclusive to my patreon supporters for a while before I release it on my github: https://www.patreon.com/posts/68614310
