I used to work at a retro game store, and the original Game Boy Tetris was by far the game that sold most consistently.
I’d love to see more that separates this from standard Tetris and leans harder into the gold digging. Maybe clearing a line could blast out the blocks below so you can drill down toward the gold?
Anyway, your game got me thinking, which is always a good sign. Very cool achievement building this from scratch. Kudos!
