Let's get this out of the way, this is by far the worst 8-bit Nintendo console port of Tetris. What kills this version is the controls as the Famicom version is based on various computer ports Bullet Proof Software also developed but for some reason directly mapped the controls from said computer versions onto the Famicom controller. What used to be space to hard drop is now the A button and you have no way of soft dropping. You rotate by pressing the directional buttons which makes trying to play this version a chore. While it's historically an important release there's little reason to play this one now.

This is without a doubt the best game to have been released during the initial lifespan of the Famicom. The music is outstanding that sadly didn't hit as hard when it released in Scandinavia as Mr. Gimmick on the NES due to hardware differences. While it is challenging its never unforgiving as with enough practice you can easily beat this in less than an hour. Unfortunately getting ahold of an original cartridge will set you back tens of thousands of yen or a few hundred dollars but thankfully with the release of Special Edition the game can now be played on modern platforms so I'd recommend picking that release up if you want to experience this masterpiece.
