Some background: I always wanted to learn C/C++ but was too lazy to do anything other than a few simple exercises.  My friend convinced me to just join a game jam and force myself to learn.  This is the result.

Using the SDL3 framework for rendering, Doors is an extremely simple game which drew inspiration from the Tower of God scene which had participants in a room with dozens of doors, a time limit, and one rule: open a door within the time limit.
