Seemed cool, couldn't work out the rhythm stuff though, it just kind of kept going and I had no idea if I was doing anything correctly.

On the line at the bottom, you can see a small disc going from left to right; you have to press when the key’s name passes on it. You will see a particle effect if you do it right.
The other mode (where each half of the screen has top indications) is more straightforward, but maybe you did not reach it; just press when the indication reaches its name at the top.
