Mama Soybean's Delicious Oyster Sauce is a small puzzle game for MS-DOS.
It has 16 levels, stupid background story and clumsy DOS-era gameplay with
eye-hurting CGA graphics.

The game was written in C using OpenWatcom compiler.

Controls:
    Arrow keys: Move
    Enter/Space: Select in menu
    R: Restart
    Escape: Quit stage

KNOWN BUG: If you reach the level 16 without using passwords, the game will
crash after the level 15 with message "File not found". Workaround: write down
the password of floor 15, reset the game, choose "Password", input the
password and now beat the stage 15. Map 16 should load normally now.
