Here is a technical demo of my open-source game. It lacks a menu and any settings, and the graphics are highly sketchy. My main goal was to test the idea of the gameplay.
Summary:
There is a set of paired connected stones on the game field. The player's task is to untangle them and place them in the hole at the bottom of the screen.
