Mosaic Tetris was a game played from the terminal that I made as my first introduction to the Go programming language. It is similar to Tetris, except you can put the pieces anywhere on the board and they don't fall down. The catch: the pieces cannot be rotated.
You can download Mosaic Tetris from
my main website
or, if you're already on tilde.town, play it with the command
town mosaic-tetris.
