This is fantastic, can't thank you enough for finally bringing a good Tetris version playable on the gameboy micro! This has all the best parts of the modern titles, and the soundtrack is beautifully "GBA". Even going the extra mile for 2P via link cable, I love it! You did an awesome job :)
One request: I would love to see a game track remixed from the original Tetris Theme, (or maybe remixed from the Russian folk song Kalinka to avoid any ip issues?) There's nothing like stacking blocks to the classic tune.
