Here is my simple game, written using SFML for graphics and SFGUI for GUI.
The game is a bit strange, but it's intended to be such.

The game is also localized into several languages using the gettext library.
Much attention has been paid to the GUI, all settings are applied immediately, without any "Apply" buttons.
Supports GNU/Linux and Windows, i'll also make macOS support in the future.
I used legacy opengl to make the game work even on very old hardware like my Dell Inspiron 1300.
