80x23 terminal tetris!

tinytetris.cpp

This is the 80x23 version. You control it with a (left), d (right), w (rotate), s (drop), and q (quit). It depends on curses.h (so you'll need to compile with -lcurses, and install curses if you don't already have it) and requires C++11.

tinytetris-commented.cpp

This one is almost identical to tinytetris.cpp, but not minified, and with some comments to make it easier to read (but it's still tricky to read in certain parts).
