Very original idea, and I think it gets the desired effect of people playing twister with the controller, so it could definitely be a lot of fun. However, it feels like the game doesn't always respond well to button presses, and some prompts from the terminal are hard to understand.
In addition, there isn't any narrative sense in what you do and in the reason that it's all on one controller, so it makes it feel like the game is just an excuse to make you play twister with the controller, rather than having it feel like a natural result of a game mechanic (For instance, in overcooked the mechanics allow for one player to do everything, but the way the different mechanics work makes it so that teamwork is greatly rewarded)
With a few tweaks, I think it could be a pretty cool party game. Good luck =)
