The other day, @zorn mentioned ROM hacking which threw me back to the summer of 2018. One hot evening, I asked myself: what if Tetris only had the straight tetromino? So, I fired up my hex editor and hacked together this thing. 😅 🎮

A game of Tetris on a Game Boy Color. It looks a bit weird! There's only one type of tetromino, the straight one. The pieces on the screen form the two-letter word hi.
