Hi there! I'm new to the Tetris community, and this is my first post. I'm making a program with exactly the same physics as NES Tetris, but with more options such as a practice mode, scenario modes, that kind of stuff. Any suggestions for features?

I really like the idea, and there are some actually are working on a rom hack like it. Where our community usually communicates is at CTM discord. So if you would like to join, please do so.
