Soviet Bloc Game (C version)

While thinking about ways to make my TRS-80 model I more useable in 2019, I realized that I could not easily find a version of Tetris for it (probably because the TRS-80 came out about 10ish years before Tetris was invented), so I thought I might try to write my own after watching an episode of the 8-bit Guy where Dave does the same. I used to play the Gameboy version of Tetris all the time on my Ti-nSpire calculator thanks to the nspire hacking scene and an emulator port, so that's the style of Tetris I will try to recreate.
