commit eea5925b9021ac841cdced31f1de1f4c80bb3a32
Author: Eduardo Silva <eduardosilva@disroot.org>
Date:   Sat Oct 19 21:42:54 2024 +0100

    Added an interface to support multiple games
    
    - In the same way, I expect the addition of the ability of holding
    multiple sinks in memory like outputting to a TUI, GUI and other
    hardware devices
