Really fun concept, the introduction to the mechanic was very effective too. It does get quite repetitive after the 10th or so dance, something like different levels with slight adjustments to the mechanics (like moving hotspots?) might add some spice.

Was surprised at the concept. Some of the markers appeared half outside of the screen, making it difficult to pick up again. Maybe for an extra challenge, the timer could become smaller and smaller. 

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

There is a good introduction to the mechanic, but the game seems endless at the moment; the goal isn't super clear yet. Maybe if there is a chance of escape or a penalty for not completing the task in time the player gets a bigger sense of purpose. Very original tho :)
