Very fun, but could use some polish. Controls need improvement. A single key for rotating would work better (arrow up is the most intuitive and indeed I keep hitting it and accidentally "storing" a piece for later, which is a great concept but should be bound to a different key since the arrow keys convey movement). Should show instructions in the same page as the actual game. In fact, the home page should be the game, with the other stuff tucked away (see e.g. the Wordle page for one potential UI/UX approach). Graphics could use some polish, typography / CSS too

The up arrow to store was the biggest problem for me. I ended up doing this about 10 times in about 40 pieces, just because it's muscle memory from Tetris.

Same here. Also, such games would certainly benefit from single-hand operation in mind. I'd prefer UP for rotation, DOWN for drop, and, maybe, PgUP/DN for L/R rotation, END for hold. And similarly on the WASD side of the keyboard, so either hand may be used optionally. Or even for one-keyboard multiplayer. )
