A match three game.
This app needs OpenGL4 or OpenGL-ES3.0 or higher, and Qt5. It was developed on Fedora 30, but should run on any OS supported by Qt5, including Android, iOS and even webbrowsers.
I created the game pieces myself, as should be clear from their "artistic" quality. To accent my work, I use the great font "Chalk Dash" font, which is free for non-commercial use, more information here. The background image is creative commons.
