Thanks for feedback!
I think this is our mistake - we had to make a screen "how to play". We will take this into account in future projects.
If you want to try again, this is an instruction. When you clicked "dance" button and the main screen started, where the cat is walking on the table, you need to push arrow buttons. On the top appear arrows and you need to push current arrow buttons when arrows on the top reach the flashing circle.
If it doesn't work - please comment, we will try to search the problem!
