Game of binary rain for the terminal. This is the terminal version of 0RA1N. The goal was to provide a gameplay experience as close as possible to the original. Obviously, the terminal requires some adjustments.

Type 0 or 1 to clear digits in falling strains of rain. Clear the digits in sequence to clear the strains. Keep the strains from reaching bottom of screen. Easy. Right?

Made with lots of love in Nim. Fast compilation, small binary, zero dependencies.
