I have played Tetris DS with the GamePad and it's very comfortable

the gamepad is more comfy than whatever the hell is that small d pad on the gamecube controller plus the pro controller dpad hurts my wrist for a long period of time

yeah the GameCube D-Pad is really bad... i do agree..

ps4/5 controllers are my favourite to play tetris with, if i have to rank the controllers I used ps4/5 > gamepad > 3ds > pro controller > joycons > gamecube controller

i forgot about the wiimote and classic controller because of tetris party

I've played Puyo Pop Fever on the GameCube with a GameCube controller myself. It is absolutely not ideal lol

I've played Puyo Puyo plenty of times with a GameCube Controller and to me personally, it's not that bad once you get used to it.
