not really... besides the instadrop, technically you can softdrop by holding down, but it only goes as fast as pico-8's built-in keyboardlike autorepeat. and the game does speed up on its own eventually, but the curve is pretty bad... it so yeah, some maneuvers are pretty annoying right now.
i did my best to figure out the controls for a game with pieces of wildly varying sizes, but i focused on making the game playable at all first. I'll keep working on it later, because i like this game!
