I appreciate the tutorial! clearly explains the mechanics
I think it's also good you added a score, does make the game have an objective!
I had a bit of trouble every now and then since it can get unclear sometimes which hand/foot is left or right, I think it'd help to have some way to differentiate between the hands and feet, like with a ring on one hand or something like that
I think it'd especially be cool if you actually had to break/fight things, if I'm allowed to spit out an incredibly generic idea, something like a police guard being a target for the hands/feet which slowly approaches you and you have to fight that guard off before it reaches you
